The Wisconsin Department of Transportation (WisDOT) is in the process of developing plans for proposed improvements to the US 41 intersection with Kasal Lane/Kamm Road in Marinette 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 to the feasible alternatives.
Project location
The project is located at the US 41 intersection with Kasal Lane/Kamm Road in the town of Grover in Marinette County.
Public meeting
WisDOT held a public involvement meeting on February 26, 2025. A video of the presenation is available at the link below. The same information contained on this project website was presentated at the PIM.
Project purpose and need
The intersection has a history of fatalities and severe injury crashes. From 2009 to 2023, there have been 42 crashes. Improvements are needed to reduce the number of crashes at the intersection, in particular right-angle crashes which have resulted in five deaths. The purpose is simple - Create a safer intersection.
- 5 Fatalities
- 5 Severe Injuries
- 13 Minor Injuries
- 19 Property Damage Only
Improving Safety by Reducing Conflict Points
A conventional intersection on a 4-lane divided highway has 42 conflict points (see diagram). Each conflict point has some level of exposure and risk which can lead to crashes. Crossing conflicts occur between drivers within different traffic streams. These conflicts have an increased potential for right-angle crashes which often result in severe injuries. These crashes typically occur on the far side of the 4-lane divided highway when a driver attempts to cross the highway or turn left onto the divided highway.
Proposed improvements
This project received federal Highway Safety Improvement Project (HSIP) funding in 2024. The federal safety funds are only given to intersections experiencing significant safety issues. This intersection is in the top 5 percent of the poorest-operating intersections in Wisconsin.
- Proposed improvements include reconstructing the US 41 intersection. The public is encouraged to carefully review the below alternatives and provide comment.
- Following public comment, WisDOT will choose one of the four alternatives below.
Alternative development - Four Alternatives
At intersections on 4-lane divided highways that are experiencing safety issues, engineers evaluate alternatives to improve safety which can include reducing conflict points. Alternatives with varying levels of direct access from the side roads to US 41 have been developed for consideration. A preferred alternative has not been identified. Input from users of the US 41 corridor, in particular this intersection, will be factored into the decision-making process.
Proposed Alternative: T-Intersection: This alternative removes direct access from Kamm Road to US 41. Access from Kasal Lane to both northbound and southbound US 41 would be maintained.
RCUT Intersections
Two RCUT intersection alternatives have been developed for the project. A Restricted Crossing U-turn (RCUT) intersection is a type of Reduced Conflict Intersection used primarily on 4-lane divided highways. RCUT intersections differ from conventional intersections by re-routing left-turn and through vehicles from the side road. Motorists approaching the divided highway from the side road are required to turn right and then make a U-turn at a designated median opening. This reduces the conflict points.
Proposed Alternative: Restricted Crossing U-Turns (Direct Access from US 41):
This alternative leaves direct access to both Kasal Lane from US 41 Southbound and Kamm Road from US 41 Northbound. Motorists are required to make a U-Turn to access US 41 Northbound from Kamm Road and US 41 Southbound from Kasal Lane or to make a through movement from Kamm Road to Kasal Lane.
Proposed Alternative: Restricted Crossing with U-Turn (No Direct Access from US 41)
This alternative removes direct access to both Kasal Lane from US 41 Southbound and Kamm Road from US 41 Northbound. Motorists are required to make a U-Turn to access the side roads from US 41 or to access US 41 northbound from Kamm Road and US 41 southbound from Kasal Lane or to make a through movement from Kamm Road to Kasal Lane.
Proposed Alternative: Restricted Crossing (Full Median Closure): The intersection would block off the median removing left turns from US 41 to both Kasal Lane and Kamm Road. Left turns onto US 41 would also be eliminated. Right-into and right-out of movements would still be allowed onto Kasal Lane from US 41 northbound and onto Kamm Road from US 41 southbound.
For quick review of all four alternatives, please download the below project alternatives document.
Traffic Impacts
US 41 will be reduced to one lane of traffic in each direction during construction. Temporary lane closures and/or access restrictions are anticipated on Kasal Lane and Kamm Road.
- Access will always be maintained for residents, businesses and emergency services.
- The duration of these impacts will vary based on the selected alternative.
Real estate
Minor real estate acquisitions may be needed. The amount and location will vary based on the selected alternative. A member of the real estate team will be in contact with any property owner affected.
Schedule
- Public Involvement Meeting: February 26, 2025
- Real Estate Acquisitions (if needed): Summer 2026
- Final Plans: Spring 2028
- Anticipated Construction: Summer 2029
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
- Staying informed
- Keeping customers informed
- Tips for businesses
WisDOT’s In This Together website is located at
www.wisconsindot.gov/Together.
Temporary Business Signing
Businesses impacted by highway closures and detours will have an opportunity for temporary business signage during construction. To learn more about temporary business signing, please see our
In This Together - Temporary Signing Application.
