The Wisconsin Department of Transportation (WisDOT) is in the process of developing plans for proposed improvements at the intersection of WIS 26 and County TC in the towns of Springvale and Waupun in Fond Du Lac County. The purpose of this website is to provide information regarding the proposed improvements, describe the potential impacts it would have on the community, and offer an opportunity for public comment.

Project location
Project ID 1110-17-00 is located at the intersection of WIS 26 and County TC between Rosendale and Waupun in the unincorporated community of Ladoga and, in the towns of Springvale and Waupun in Fond Du Lac County.
Project purpose and need
The purpose of the proposed project is to improve safety at the intersection of WIS 26 and County TC while providing acceptable traffic operations.
The need for the proposed improvement is to reduce the number and severity of crashes at the intersection, particularly right-angle crashes.
- From 2018 and 2022, the intersection experienced nine total crashes resulting in four injury type crashes.
- Right angle crashes accounted for four of those nine crashes, with three resulting in injuries.
- Contributing factors to the current crash trends include drivers’ failure to pick adequate gaps when entering the intersection from County TC.
2023 Study
A study completed in October 2023 reviewed alternatives for improving safety at the intersection. A traffic signal and roundabout were evaluated for improving the intersection. The intersection did not meet the required warrants for a traffic signal and a single-lane roundabout was recommended to address the high rate of serious crashes.
Anticipated benefits
The proposed action will improve safety for drivers by decreasing speeds through the intersection and eliminating right angle crashes resulting in fewer severe crashes at the intersection while maintaining acceptable traffic operations.
Proposed improvements
The proposed roundabout would consist of single-lane entries on all approaches. Major activities that would occur with the proposed action include:
- New asphalt pavement
- New curb and gutter
- OSOW/Truck accommodations – mountable truck apron and overtracking pads
- New signing and pavement marking
- Intersection lighting
- New culvert and storm sewer installation

Traffic impacts
The WIS 26 and County TC intersection will be CLOSED during construction and a detour route for WIS 26 will be posted. 
- Detour: The tentative detour route includes US 151, I-41, and WIS 23.
- Local access to properties and businesses within the project limits will be maintained throughout construction.
Schedule
- Public Involvement Meeting on July 30, 2025.
- Environmental Document approval in September 2025.
- Real estate acquisition is anticipated to begin in fall of 2026.
- Design is on-going and will continue through 2028.
- Construction is currently scheduled for spring/summer 2029.
Real estate
Real estate acquisitions will be required, in the form of permanent right of way and temporary limited easement (TLE), to accommodate the intersection improvements. A member of the real estate team will contact affected property owners.
Business Resource: WisDOT’s In This Together program
WisDOT recognizes businesses located in work zones or impacted by detour routes have special needs. WisDOT's In This Together program is offered to business, organizations and community leaders as an idea source as they plan for road construction in their area. It includes promotional examples, case studies and a specially designed Business Coordination Guide with information on:
- Planning ahead
- Keeping customers informed
- Tips for businesses
- Temporary business signing during construction
- Businesses impacted by highway closures and detours will have an opportunity for temporary business signage during construction.
