Hwy 43 repaving

Rushford to Mabel


About this project


In 2022, MnDOT will repave and replace culverts on Hwy 43 from Rushford to Mabel. This project was a flex project, meaning construction could have begun as early as 2022 or move to 2023. The funding was secured and construction is scheduled from May 23 to mid-October 2022.

Summary of work

  • Repave 22 miles of Hwy 43
  • Stabilize three areas of eroding slopes and shoulders
  • Replace all guardrail
  • Replace 11 centerline drainage pipes
  • Repair 55 centerline drainage pipes

Additional details

This project will address the erosion along the hillsides and near the roadway. Three areas have been identified where work will be done to stabilize the slopes and maximize the roadway width as much as possible. This section of Hwy 43 is an extremely rugged area and poses many engineering challenges, especially in balancing the needs of the highway and impacting private property.

This is a pavement preservation project, so there is not enough funding to change the geometrics or remove sharp curves. However, MnDOT will repair several locations where the shoulder/road needs repair or reinforcing adjacent to ravines. Work will improve and stabilize the shoulders, and where there is width available, increase usable shoulder widths of 2 to 4 feet. Due to the steep slopes, there will still be areas where the roadway shoulder width will be minimal and the guardrail will be near the edge of the 12-foot travel lane. All guardrail will be replaced.

Traffic impacts

The replacement of culverts and pipes includes excavation of the road which requires detouring traffic. Two detours will be used during this project.

  • The Section A detour, which includes Co. Rd. 25 and Co. Rd. 37, will be used to direct travelers around Hwy 43 when Section A is under construction.
  • Once Section A opens to traffic, then construction will begin on Section B. The Section B detour includes county roads 37, 10, 12, and 21 and Hwy 52.

When the pipe work is finished and the detours are lifted, delays may still be possible while the crews repave the roadway.

Individuals, businesses and first responders will have the ability to reach their destinations. The culverts will be replaced in an order that allows access. Individuals may be directed to access or exit a property from a single direction. Questions or comments can be sent to the project team.
