2026 SS4A GRANT APPLICATION 1 St. Croix County, WI Rural Highway Safety Project OVERVIEW St. Croix County, Wisconsin (herein referred to as “the County”) is requesting $4,666,135 ($3,705,674 for implementation projects, and $960,461 for supplemental planning projects detailed at the end of this application) in discretionary funding through the FY 2026 Safe Streets and Roads for All (SS4A) Implementation Grant program. The requested funds will support the deployment of low- cost, high-impact strategies grounded in the Federal Highway Administration’s (FHWA) Proven Safety Countermeasures (PSCs) with a focus on the Safe System Approach to prevent fatalities and serious injury crashes, particularly in rural communities, as well as supplemental planning dollars for the completion of four corridor studies along the most hazardous of the County’s highways. The St. Croix County, WI Rural Highway Safety Projects (herein referred to as “the Project”) will improve safety of seven segments comprising over 84 miles of the most dangerous rural county trunk highway (CTH) segments, six of the most dangerous intersections, and eight hazardous curves across the county (see Figure 1). Each of these projects have been identified in the County’s Safety Action Plan (SAP) adopted in 2025. Figure 1 Project Location Map In total, the Project is expected to prevent 5.2 fatal and 26.2 serious injury crashes over the next 20 years, resulting in a benefit-cost ratio (BCR) of 22:1 (detailed in Table 1).

According to FARS data, St. Croix County experienced 51 fatal crashes between 2019-2023. Data collected from the WisTransPortal System managed by the Wisconsin Traffic Operations and Safety Laboratory (TOPS Lab) identified an additional 16 fatal crashes in 2024-2025. Further analysis shows 297 serious injury, 1,224 minor injury, and 926 possible injury crashes between 2019 and March 31, 2026, according to the TOPS Lab data (see Figure 2). Figure 2 Crashes in St. Croix County (2019-2026) This application focuses on safety improvements along County Highways (CTHs) as recommended in the County’s SAP. These improvements fall into three categories: 1) rural segments; 2) rural curves; and 3) rural intersections. The Project’s goal is to enhance safety along both the High Injury Network (HIN) and in other high- risk areas of the CTH system that have been shown in the SAP to experience a high incidence of risk factors for fatal and severe injury crashes. Each component of this Project shares the common objective of addressing safety concerns for all users of the County’s CTH network. Page 30 of 51 FY 2026 SS4A GRANT APPLICATION 3 St. Croix County, WI Rural Highway Safety Project LOCATION St. Croix County is located in northwest Wisconsin along the Minnesota border, with a 2020 Decennial Census population of 93,536. Although classified as a rural jurisdiction, the County experiences above-average population growth compared to Wisconsin in general, largely due to its proximity to the growing Minneapolis-St. Paul metropolitan area. According to the 2020 Decennial Census, the largest communities in the county include the Cities of Hudson (14,755) and New Richmond (10,079), as well as the Villages of Baldwin (4,291), North Hudson (3,803), and Somerset (3,019). The Project is located across St. Croix County, encompassing over 84 miles of improvements to seven rural CTH segments, enhancing the safety of six hazardous intersections across the county, and eight curves on rural CTHs associated either with past fatal and severe injury crashes, or locations that share similar risk factors (see Figure 1). RESPONSE TO MERIT CRITERIA SAFETY NEED Description of the Safety Problem State County City Township Figure 3 Percentage of Severe Crashes by Jurisdiction, 2019-2023 (excluding animal crashes) Source: St. Croix County, Wisconsin Safety Action Plan Between 2019 and 2023, 1,823 crashes occurred on the CTH network, accounting for approximately 28 percent of all crashes on the local system. Fatal and serious injury crashes have remained relatively stable since 2014, a trend that can be attributed to safer roads and vehicles, as well as more stringent enforcement of existing laws and policies by St. Croix County and the municipalities within county borders. Of all fatal and serious injury crashes across the county during this period, 38.4 percent occurred on the HIN which represents less than five percent of county roadways. Overall, approximately 56 percent of severe crashes took place on roadways under local jurisdictions (Township 17 percent, City 14 percent, and County 25 percent) (see Figure 3). On average, if a driver experiences a crash on any roadway in St. Croix County, the likelihood of that crash being fatal or severe is about two percent. However, for crashes occurring specifically on rural CTHs (the focus of this grant application), this figure increases to over three percent. This is primarily due to factors such as high speeds, vehicles running off roadways at curves on CTHs, and crashes at key intersections. Geospatial Risk Visualization Utilizing data from the TOPS Lab, the County has identified the crashes that have occurred in direct coincidence with the proposed projects identified within this application. According to this data, three fatal crashes and 18 crashes resulting in serious injuries occurred out of a total of 192 crashes between 2019 and 2023. Fatalities and serious injuries occurred from crashes where vehicles ran off the roadway along dangerous curves and head-on crashes with another vehicle or with a fixed object. Between 2019 and 2023, 51 fatal crashes took place on St. Croix County roadways. An additional 16 fatal crashes occurred between 2024-2025 (see Figure 4). Page 31 of 51 FY 2026 SS4A GRANT APPLICATION 4 St. Croix County, WI Rural Highway Safety Project Figure 4 St. Croix County Fatal Crashes (2019-2025) Assessing Safety Risk The SAP goes beyond traditional crash analysis by employing a “Systemic Safety Analysis” to identify high-risk priority locations. These locations are ranked based on their correspondence with multiple risk factors (defined as characteristics correlated with an increased likelihood of severe injury or fatal crashes). These risk factors are represented by stars (see Figure 5), which contribute to creating a prioritized ranking for projects that form the basis of this grant application. This type of analysis is especially useful for examining severe and fatal crashes in aggregate, helping to identify common patterns when crashes appear scattered randomly on a map. The Systemic Safety Analysis utilizes the following process: 1. Establish the county’s roadway network 2. Collect data on roadway geometrics and crashes 3. Identify Risk Factors (elements that contribute to crashes) 4. Prioritize county segments, intersections, and curves based on risk factor assessments 5. Assign project recommendations to high- priority county segments, curves, and intersections. Figure 5 Risk Factors Informing the High Injury Network (as defined in SAP) Page 32 of 51 FY 2026 SS4A GRANT APPLICATION 5 St. Croix County, WI Rural Highway Safety Project SAFETY IMPACT The High Injury Network All projects included in this application fall along the High-Injury Network (HIN) established in the SAP. The HIN (see Figure 6) is based on historical crash evaluation from 2019 to 2023 on all non-freeway and non-limited access highways across the county. Although only about 85.8 miles (4.3 percent) of county roadways are included in the HIN, these roads account for 38.4 percent of fatal and serious injury crashes countywide. The County followed a six-step process to develop its HIN, as follows: 1) Compile the crash data; 2) Create the base network; 3) Divide the network into “short” (i.e., 0.1-mile) segments and “long” (corridor-level combination of short segments) windows; 4) Assign crashes to long windows; 5) Calculate crash scores; and 6) Set a threshold for inclusion in the HIN. Appendix D of the SAP provides a more detailed description of the six- step process. Figure 6 St. Croix County High Injury Network (HIN) Use of Low-Cost, High-Impact Strategies The Project is distinct and strategic in its ap- proach to implementation. Rather than concen- trating solely on one corridor or specific local areas of concern, it closely follows the HIN and the findings of the SAP’s Systemic Safety Analysis to identify targeted improvements. Figure 7 Core Elements and Principles of the Safe System Approach The result is a broad investment in low-cost, high-impact safety strategies across CTHs, aimed at systemically improving rural seg- ments, curves, and intersections across the 722 square miles that make up the county. Most of the proposed improvements are low-cost, and all have high-impact. The most utilized strate- gies are documented below: Lighting The Project will enhance lighting at five intersections and one curve in the County. Proper lighting of intersections and priority crossings are one of the most easily implementable and cost- effective safety improvements with a proven track record of crash reduction. The safety benefits of adequate lighting at rural intersections and on rural highways are well-documented. FHWA PSCs demonstrate that lighting can reduce nighttime crashes at rural intersections by up to 38 percent, and nighttime pedestrian crashes at all intersections by 42 percent, corresponding to Crash Modification Factors (CMF) of 0.62 Page 33 of 51 FY 2026 SS4A GRANT APPLICATION 6 St. Croix County, WI Rural Highway Safety Project and 0.58, respectively. Lighting will enhance roadway safety at five intersections of CTHs across St. Croix County. Enhanced Delineation for Horizontal Curves The Project will implement chevrons and signage to delineate eight dangerous curves across St. Croix County. To address hazards presented by curves on high-speed CTHs, the Project implements improvements at eight hazardous curves throughout the county. The following low-cost, high-impact strategies are proposed as part of the Project (see Table 2). These facility treatments can be applied individually or in combination with other roadway improvements, either in advance of or within the curves. Table 2 Strategies for Enhanced Delineation for Horizontal Curves Strategies for Rural Curves In Advance of a Curve Within a Curve Pavement markings (standard width or wider) Yes Yes In-lane curve warning pavement markings Yes -- Chevron Signs -- Yes Enhanced Conspicuity (i.e., larger, fluorescent, and/or retroreflective signs) Yes Yes Sequential dynamic chevrons -- Yes FHWA’s PSCs prove that these low-cost, high-impact treatments are effective at reducing both fatal and total crashes. For example, chevron signs lead to a 16 percent reduction in non-intersection fatal and injury crashes at curves, and a 25 percent reduction in night-time crashes. Fluorescent curve signs are also proven to reduce rural non-intersection, head-on, run-off-road, and sideswipe crashes by 18 percent. The Project includes Safety Improvements at a critical curve where a fatal crash took the life of eight-year-old Owen Hailey in December 2025. Rumble Strips Longitudinal rumble strips are proposed along the nearly 29 miles of the most hazardous CTH segments in this Project, both along the center line and the edgeline. Rumble strips are an extremely cost-effective PSC, with economic analyses indicating a benefit-cost ratio of over 100. These raised or milled elements alert drivers through vibrations and sound that their vehicles have either drifted to the side of the road or into oncoming traffic. Shoulder rumble strips are shown to reduce single-vehicle, run-off-road fatal and injury crashes by 13 to 51 percent on rural roadways (corresponding with a CMF of 0.87 and 0.49). Centerline rumble strips yield even more safety benefits, reducing head-on Page 34 of 51 FY 2026 SS4A GRANT APPLICATION 7 St. Croix County, WI Rural Highway Safety Project fatal and injury crashes on rural roads by 44 to 64 percent on rural roadways (corresponding with CMFs of 0.56 and 0.36). Wider Edgelines The Project also includes widening of edgelines from four inches to a maximum width of six inches along over 84 miles of hazardous CTH segments. Wider edgelines increase the visibility of the travel lane and yield a meaningful reduction in crash frequency and severity. Wider edgelines can yield a 37 percent reduction in fatal and injury crashes on rural roads (corresponding with a CMF of 0.635). These are especially cost- effective PSCs, yielding a total benefit-cost ratio of 25:1 for fatal and serious injury crashes on rural roadways, per the Idaho Department of Transportation (2018). Use of Evidence-Based FHWA Proven Safety Countermeasures Roundabout One of the improvements of this Project is the conversion of the intersection of CTHs A and U into a roundabout. Roundabouts are a comprehensive solution to managing intersection traffic in both urban and rural settings and offer multiple benefits. They not only calm traffic speeds but are also proven to reduce delays and queuing compared to traditional intersection treatments. Most importantly, roundabouts are highly effective in reducing fatal and serious injury crashes. Converting two-way stop-controlled intersections to roundabouts has been shown to result in an 82 percent reduction in fatal and injury crashes, corresponding to a CMF of 0.18. Measuring Persistent Safety Impacts & Benefits The countermeasures at high-risk curves, roadway segments, and intersections along the St. Croix County HIN will deliver both immediate and long- lasting safety benefits. According to a Benefit- Cost Analysis (BCA) conducted for the Project, this suite of improvements will save lives among St. Croix County residents in both the near and long-term, while preventing many more severe, life-altering injuries due to traffic crashes. As previously mentioned, benefits were monetized for a BCA completed for the Project and were based on the following CMFs (see Table 3): Table 3 Applicable Project CMFs used for Project Benefit-Cost Analysis Calculations CMF ID Countermeasure CMF Value Applicable Severity (KABCO) PSC Citation 4737 Enhanced Edgelines 0.635 KABC Wider Edge Lines Park et al.

The installation of High Friction Surface Treatments (HFSTs) is planned at 14 locations. HFSTs are an FHWA Proven Safety Countermeasure that can reduce injury crashes up to 48 percent at horizontal curves. An HFST is proposed along 887 feet of CTH A. IMPLEMENTATION COSTS Summary of Costs If funding is secured, construction activities will occur during calendar years 2028 and 2029. A broad summary of costs is detailed in Table 4, while a full cost breakdown can be viewed in the Project Budget. Table 4 High-Level Project Budget (Rounded to the Nearest Dollar) Activities SS4A Request (80%) Local Match (20%) Total Project Cost Corridor Studies $960,461 $240,115 $1,200,576 Improvement of Hazardous Curves $139,389 $49,847 $249,236 Improvement of Hazardous Segments $803,912 $200,978 $1,004,890 Improvement of Hazardous Intersections $2,702,373 $675,593 $3,377,967 Total (Construction only) $3,705,674 $926,419 $4,632,093 Total (Inc. Supplemental Planning) $4,666,135 $1,166,534 $5,832,669 If awarded, this Project would mark the first application of a High-Friction Surface Treatment (HFST) in St. Croix County, per the Wisconsin Department of Transportation. Reasonableness and Necessity of Costs Planning-level cost estimates were prepared in 2024 by a certified professional engineering firm as part of the SAP development process. These estimates were subsequently revisited to reflect constructability considerations and current bid prices. Costs were then escalated to 2028 dollars using an assumed annual inflation rate of four percent. Engineering and administrative costs are estimated at 10 percent of total construction costs. Any cost overruns will be funded by St. Croix County funds. The County Highway Department has considered all relevant factors, including materials, labor, and potential contingencies to ensure that the cost estimates presented in this grant application are both reasonable and necessary to complete the Project. St. Croix County has an established track record of accurately estimating the costs of capital projects of similar size and scope to the proposed project. Effective Use of Federal Funds The Project represents an effective and responsible use of federal funds by deploying proven systemic safety countermeasures along St. Croix County’s HIN considering the findings in the SAP. Rather than addressing crashes after they occur, this Project proactively targets the most dangerous curves, segments, and intersections along St. Croix CTHs to maximize long-term fatal and The Project will prevent 5.2 fatal crashes and 26.2 serious injury crashes over a 20-year analysis period, resulting in an undiscounted benefit-cost ratio of over 22:1. Crash costs by severity are from the USDOT BCA Guidance for Discretionary Grant Programs (2024 dollars). This analysis conservatively assumes no traffic volume growth and monetizes only fatal (K) and serious injury (A) crashes. Page 36 of 51 FY 2026 SS4A GRANT APPLICATION 9 St. Croix County, WI Rural Highway Safety Project serious injury crash reduction benefits per federal dollar invested. By focusing on scalable, evidence-based countermeasures that can be implemented readily within the County’s existing right-of-way, this Project achieves broad and substantial safety improvements in a cost-effective manner, yielding an effective benefit-cost ratio of over 22:1 (a net benefit of over $101 million in 2024 undiscounted dollars). ENGAGEMENT AND COLLABORATION Preventing Roadway Fatalities and Serious Injuries in Rural Communities According to FHWA, while public concern about speeding is focused on high-speed interstate highways, 87 percent of 2022 fatal speeding- related crashes took place on non-interstate highways. The Project therefore explicitly focuses on rural CTHs, aiming to reduce crashes at key segments, curves, and intersections along the CTH system. St. Croix County is a rural jurisdiction whose population is forecasted to increase despite projections showing that Wisconsin’s population will decrease. The county’s population is projected to grow from 93,536 in 2020 to 102,980 by 2050 (Wisconsin Department of Administration population projections), a total increase of 10 percent. This growth contrasts with the state’s overall projected decline of over three percent during the same time frame. The county’s growth is driven by the growth of the nearby Minneapolis- St. Paul urbanized area. This underscores the critical importance of this project not only for current residents, but for future drivers in the next 25 years that will travel along the county’s rural roadways. Demographic Considerations According to the 2020 Decennial Census, 14,375 St. Croix County residents (15.4 percent of the population) were age 65 or older. The Wisconsin DOA projects this number will nearly double by 2050 to 27,715, representing 25.9 percent of the county’s population by that time. This demographic trend is critical for traffic safety. According to the National Highway Traffic Safety Administration (NHTSA), older Americans consistently experience higher fatality rates than younger age cohorts. This is attributable to unique safety challenges associated with aging like reduced visual capacity (especially at night), slower reflexes, and decreased physical fitness. As this population cohort grows disproportionately in the county and across the United States, the Project’s countermeasures that emphasize visual cues like improved lighting, chevrons, arrow boards, edgelines, and signage will play a critical role in fostering road safety for older adults. Engagement Plan St. Croix County will engage communities through all phases of the Project, from planning, design, and through construction. This will include activities such as Public Involvement Meetings (PIMs) to engage interested parties and adjacent property owners following the example of similar meetings held for recent construction projects across the County. The St. Croix County Highway Department will also leverage its long-standing partnerships with the 21 townships across the county and their respective governments to reach and involve all affected residents and businesses. During the construction season, St. Croix County maintains a public website that is updated weekly with information on ongoing road construction projects and advertised on the County’s social media platforms. The website also provides details about the County’s and the State’s long- term construction plans, as well as public safety information related to work zones, including guidance for both drivers and those working in or near the roadway, such as flaggers and equipment operators. Community & Stakeholder Engagement Community and stakeholder engagement are critical pillars of the SAP and by extension, the Project, ensuring that the recommendations address the community’s most significant concerns. The most extensive community engagement took place in Summer 2024, when the County hosted a “pop- up” event at the St. Croix County Fair, launched an interactive web map, and ran an active social media campaign. In total, 67 attendees participated in the County Fair exercise, and the project team received 326 online comments. Page 37 of 51 FY 2026 SS4A GRANT APPLICATION 10 St. Croix County, WI Rural Highway Safety Project Figure 8 St. Croix County Fair Engagement Board (July 18, 2024) Source: St. Croix County, Wisconsin Safety Action Plan Speeding and aggressive driving were the top traffic safety concerns expressed at the County Fair, followed closely by issues related to intersections (see Figure 10). This Project has been thoughtfully designed to directly address all three of these concerns. Leveraging Partnerships While all components of the Project are located on CTHs within the County’s jurisdiction, their implementation will ultimately impact the 21 townships, 10 villages and four cities that make up the County. The St. Croix County Highway Department will work collaboratively with its municipal partners to ensure that the design and construction phases achieve the Project’s intended safety outcomes while avoiding unintended negative impacts on rural communities and the traveling public. The Highway Department will also proactively engage with potentially affected property owners to identify any right-of-way (ROW) concerns (however unlikely those may be) and implement appropriate mitigation strategies to minimize or eliminate adverse effects on businesses and the broader community. PROJECT READINESS TECHNICAL CAPACITY The St. Croix County Highway Department guarantees that all necessary activities will be completed within five years of grant agreement as outlined in the FY 26 SS4A NOFO. County staff have extensive experience delivering projects funded through general funding, and construction projects of similar scope and size, on time and within established budgets, demonstrating prudent use of federal dollars, particularly through the Highway Safety Improvement Program (HSIP), Surface Transportation Program (STP), and other state and federally funded infrastructure initiatives. Additionally, the County has experience implementing chevrons, signage, edgeline improvements, rumble strips, and lighting across the CTH network as part of both ongoing systemic safety initiatives and routine roadway maintenance activities. This familiarity with design standards demonstrates evidence of the County’s ability to efficiently deliver the proposed improvements on a county-wide scale. Additionally, the County has committed to providing a 20 percent local match demonstrated through the letter of commitment included in this application. REQUIRED APPROVALS, ASSESSMENT OF PROJECT RISKS, & MITIGATION STRATEGIES A Class II action (Categorical Exclusion, or “CATEX”) is expected for the Project, as no ROW or wetland impacts are anticipated. The County also recognizes the possibility of unexpected delays due to funding and weather-related events. Any unexpected cost increases beyond the grant award will be paid by St. Croix County using local funding. The County is well-versed in delivering large- scale projects completed through the National Environmental Policy Act (NEPA) review process. All proposed projects and strategies will conform to USDOT, AASHTO, and WisDOT standards for design. All property and ROW acquisitions, as needed, will be completed in accordance with 49 CFR Part 24 and other applicable federal regulations. Page 38 of 51 FY 2026 SS4A GRANT APPLICATION 11 St. Croix County, WI Rural Highway Safety Project SUPPLEMENTAL PLANNING ACTIVITIES SCOPE OF WORK St. Croix County is requesting $960,461 in FY 2026 SS4A Program Grant Supplemental Planning funds for the completion of four corridor studies of the county’s most hazardous CTHs (see Figure 10). All four corridors pose their own distinct land use and safety contexts and challenges, and all cross through multiple municipalities. The scope of services is similar for each of the four plans and would involve long-range transportation planning for each corridor. The plans would document existing conditions of both traffic and land use and evaluate how future growth and forecasted future traffic would affect the safety, operational efficiency, mobility, and capacity of each corridor. Work would include roadway and intersection operational analysis, crash and safety analysis, access management strategies, data collection, and traffic forecasting. Each plan would provide recommendations that would detail targeted improvement of intersections, guidance on consolidating access points, signage and striping guidance, and other recommendations intended to ensure that the four corridors accommodate the future growth of St. Croix County (which is expected to outpace that of Wisconsin as a whole) while also providing a safe and efficient corridor for the traveling public regardless of their mode of travel. The plans also intend to provide a high-level environmental scan of the planning areas, while stopping short of formal NEPA documentation. All plans will be informed by meaningful public engagement at each step of the planning process. Each plan was scoped and adjusted to 2028 dollars (assuming an annual inflation rate of four percent). The County wishes to emphasize to USDOT its willingness to accept a partial award. With this possibility in mind, the County has ranked the following in corridors in order of priority, with “1” indicating the highest priority (see Table 6): Table 6 Proposed Corridor Studies (in order of priority) Priority Corridor Cost (2028 Dollars) 1 CTH A (US 12 to Richmond Way) $324,480 2 CTH E (WIS 35 to CTH A) $292,032 3 CTH I (CTH A to Spartan Drive) $292,032 4 CTH F (CTH M to CTH FF) $292,032 2026 2027 2028 2029 Q2-Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q1-Q3 FY 26 Grant Submittal Grant Agreement Preliminary Engineering Environmental Completed Final Design Complete Permitting; Bid Date Construction PROJECT SCHEDULE The County anticipates construction will begin in Summer 2028 and will be completed by Fall 2029. All major project and strategy milestones are identified in the schedule below (see Table 5). Table 5 Project Schedule Page 39 of 51 FY 2026 SS4A GRANT APPLICATION 12 St. Croix County, WI Rural Highway Safety Project ROADWAY SAFETY ISSUES ADDRESSED From 2019 to the present day, each of the four corridors have unfortunately experienced a great concentration of crashes, cumulatively resulting in five fatal crashes, 25 serious injury crashes, and a total of 1,088 crashes (see Table 7). These account for 28 percent of fatal crashes, 32 percent of crashes resulting in serious injuries, and 35 percent of total crashes on CTHs. As stated previously in this application, head-on crashes with oncoming vehicles and vehicles rolling off the roadway are prominent contributing factors to crashes resulting in fatalities and severe injuries. These corridors are also the four most prominent corridors on the HIN established in the St. Croix County SAP. While the low-cost, high-impact infrastructure treatments included in the Project will yield immediate and significant safety benefits, long- term corridor planning is needed along these roadways so that these CTHs remain safe and efficient roadways for the traveling public as St. Croix County communities continue to grow in the coming decades. INFORMING THE SAFETY ACTION PLAN The findings and recommendations in each of the four corridor plans will bring new infrastructure recommendations and insights based on the most recent data and best practices, and in consideration of timely development and growth trends. SAPs are intended to be routinely revisited after improvements are made to the HIN and new crash data becomes available. These corridor studies will be guided by engagement, collaboration, and sound safety analysis based on evidence-based strategies. These corridor studies will inform the SAP, which will continue to be grounded in the following components as established by USDOT: leadership commitment and goal setting; planning structure; safety analysis; engagement and collaboration; policy and process changes; strategy and project selections; and progress and transparency.

In these areas, parked vehicles reduce sight distance, impede traffic operations, interfere with snow removal and routine maintenance activities, and create hazards for both motorists and Highway Department personnel. Many of these locations have experienced increasing roadside parking associated with recreational activities, special events, or other recurring uses that were not anticipated when the roadways were originally designed. The proposed ordinance would establish permanent no-parking restrictions on specific segments of county highways where engineering evaluation and operational experience have determined that parking presents an unacceptable safety risk or significantly impacts the County's ability to maintain the roadway. The ordinance is intended to improve public safety, preserve the efficient operation of the transportation system, and provide law enforcement with clear authority to address parking violations in these designated locations. The Highway Department will periodically review parking conditions throughout the county highway system and, as traffic patterns, roadway conditions, and land uses evolve, may recommend modifications to designated no parking areas when such changes are determined to be in the best interest of the safety of the traveling public and the efficient maintenance of the county highway system.

Based on the initial critical finding and a subsequent evaluation by a structural engineering consultant, the bridge was posted at a reduced load limit of 15 tons in March 2026. During the inspection and subsequent evaluations, staff also observed an unexpectedly high volume of commercial and heavy truck traffic using CTH D between US 12 and STH 64. Traffic Analysis Following these observations, Engineering Division staff deployed traffic counting equipment along CTH D to better quantify traffic volumes and truck loading within the corridor (see attached map). The data indicate a higher-than- anticipated volume of heavy truck traffic utilizing this route. CTH D was originally designed to function as a lower-volume county highway with limited through heavy truck traffic. Based on the traffic counts, it appears that a significant number of heavy trucks are using CTH D as a through route between US 12 and STH 64. This traffic includes vehicles operating under oversize/overweight permits issued by the Wisconsin Department of Transportation (WisDOT). Infrastructure Concerns Highway Department staff remain concerned about the increasing volume of heavy truck traffic on this corridor. CTH D is exhibiting advanced pavement deterioration, including rutting, indicating that the roadway is likely experiencing traffic loading beyond what it was originally designed to accommodate. Continued heavy loading will accelerate deterioration of both the roadway and associated structures, increasing future maintenance and replacement costs. Bridge Closure Evaluation On June 25, 2026, the County was forced to close the CTH D bridge to all traffic after a critical structural finding was identified during an evaluation by the department's structural engineering consultant. While assessing repair alternatives, the consultant discovered additional deterioration within the superstructure. The consultant indicated that it may be possible to reopen the bridge to a single lane of traffic controlled by stop signs, with a reduced 5-ton load limit. Highway Department staff evaluated this option and considered the following factors: Safety: The roadway has a posted speed limit of 55 mph and relatively straight horizontal and vertical alignment, providing good visibility under normal conditions. Southbound drivers would be required to stop, determine whether northbound traffic was approaching, and then navigate around a barrier before crossing the bridge. Northbound traffic would also be required to stop before entering the structure. Although sight distance is favorable, the department remains concerned about driver compliance and the potential for conflicts. WisDOT reported that a similar one-lane Page 48 of 51 bridge operation near Fairchild, on a roadway with comparable traffic volumes, experienced six crashes over a three- month period, including one head-on collision and five crashes involving traffic control barricades. Winter Maintenance: Maintaining a one-lane, 5-ton crossing throughout the winter would create significant operational challenges. Standard Highway Department snowplows exceed the proposed load limit, requiring alternative equipment and maintenance procedures. This would increase operational costs while reducing maintenance efficiency and creating additional safety concerns. Load Compliance: Since the bridge was posted at 15 tons in March 2026, Highway Department staff have observed multiple heavy trucks disregarding the posted weight restriction and continuing to use the bridge. These unauthorized loads likely contributed to the accelerated deterioration that occurred between March and June. While a 5-ton posting would be more restrictive, there is no assurance that overweight vehicles would comply, creating an unacceptable risk to both the structure and the traveling public. Local Access: Closing the bridge is certainly inconvenient for local residents. However, passenger vehicles can utilize town roads located approximately one mile east or one mile west of the bridge, increasing travel distance by approximately two miles. Larger commercial vehicles have already been prohibited from legally using the bridge since the 15-ton posting was implemented, limiting the additional impact of the full closure on commercial traffic. Construction: The Highway Department is planning to replace the bridge with the goal of completing construction during the 2027 construction season. Keeping the bridge closed will allow County forces to remove the existing structure during the winter months, reducing demolition costs and lowering the overall construction contract. Conclusion Based on these considerations, the Highway Department determined that maintaining the bridge closure is in the best interest of the County and is the safest course of action for the traveling public. Staff are preparing to procure consultant engineering services to complete the bridge design, with the goal of advertising the project for an early 2027 letting and completing construction during the 2027 construction season. Page 49 of 51 FOR IMMEDIATE RELEASE 6/24/2026 Contact: Adam Kastonek – Public Information Officer Immediate Closure of CTH D Bridge Due to Deteriorating Condition St. Croix County, WI — The St. Croix County Highway Department is announcing the immediate closure of the CTH D bridge, located on County Trunk Highway D north of Woodville near 90th Avenue. The closure follows the discovery of significant additional deterioration during the development of planned bridge repairs. Detour signage is being installed to direct traffic around the closure via US-12, US-63, and CTH E. Drivers should follow the posted route and use caution while traveling through the area. In January, routine inspections identified substantial deterioration in the bridge's condition. As a result, the County ordered a load rating study to evaluate the bridge's capacity. Based on the findings of that study, the bridge was posted with a 15-ton weight limit in March. Since that time, the County has been actively developing a repair plan intended to improve the bridge's load- carrying capacity and extend its service life while funding is pursued for a full bridge replacement. During the engineering and design work for those repairs, additional deterioration was identified. Preliminary findings indicate that the bridge's condition has worsened significantly since the March load rating study was completed. Out of an abundance of caution and in the interest of public safety, the County is closing the bridge immediately until a new load rating study can be completed and the bridge's capacity reevaluated. County staff and consulting engineers are actively evaluating options to safely restore traffic across the bridge until a replacement structure can be constructed. Several alternatives are under consideration, including potential temporary traffic configurations that would utilize portions of the bridge that are in better condition. No decisions have been made at this time, and any interim solution will be implemented only after it has been thoroughly evaluated for safety. "We understand this closure will create an inconvenience for everyone who relies on this bridge,” said Robbie Krejci, St. Croix County Highway Commissioner. "However, public safety must remain our top priority. We will continue to provide updates as we complete additional engineering analyses and determine the safest path forward."
