STH 35 Reconstruction – CTH C to Laser Drive
Reconstructing a major transportation corridor in the heart of a community is no small task — especially when it spans 1.2 miles and touches businesses, churches, schools, and neighborhoods. For the Wisconsin Department of Transportation, the challenge was clear: upgrade aging infrastructure along Wisconsin 35 while keeping life moving for residents and traffic.
MSA’s design team crafted a four-stage construction plan utilizing a short detour to minimize disruption and maintain safe pedestrian access throughout the project. Special attention was given to truck turning movements and customer convenience for local businesses and convenience stores. Collaboration was key; the team worked closely with stakeholders including St. Anne’s Catholic Church and School, the post office, and the Apple River Family Campground to ensure their needs were met.
Adding complexity, the project coincided with a separate MSA-led bridge rehabilitation effort over the Apple River.
The result? A revitalized corridor that improves traffic flow, enhances pedestrian safety, and connects the community with a new multiuse path — creating a safer, more accessible route for cyclists and walkers along STH 35.

More11th Street Safety Improvements
The City of Hudson selected MSA for a key roadway safety improvement project to address poor pavement conditions and improve pedestrian safety along 11th Street from Coulee Road to Wisconsin Street. The project utilized STP-Urban funding and involved WisDOT as a third party.
This project incorporated the full WisDOT process, including producing items such as a categorical exclusion checklist (CEC), pavement design report (PDR), and design study report (DSR). The project design included an alternatives analysis phase which developed a proposed typical section along the corridor to enhance both pedestrian and bicycle safety and promote safer driving speeds due to the proximity of the corridor to adjacent schools.
MSA collaborated with the City of Hudson and the public to evaluate multiple corridor traffic-calming alternatives and ultimately settled on a road diet with the addition of a shared-use path along the west side of the project. Noteworthy aspects of the project include its adjacency to a 4(f) resource, avoidance of right-of-way impacts due to a compressed design schedule, incorporation of a water main replacement, significant construction staging, and ADA design details. Construction was complete in 2025.
