Highway 22 Mankato to Saint Peter project nearly complete; detour to be lifted by 1 p.m. Oct. 23
The Highway 22 Mankato to Saint Peter project is nearly complete, and the detour is expected to be lifted by 1 p.m. Friday, Oct. 23, according to the Minnesota Department of Transportation.
The 2025-26 project reconstructed Highway 22 from south of Blue Earth County Road 57 in Mankato to just south of the Minnesota River Bridge in Saint Peter. The project also included:
- Construction of a roundabout at Highway 22 and Hill Street near Kasota (Le Sueur County Road 21) to improve safety
- Construction of more than 80 new turn and passing lanes
- Bridge repair and replacement
- Channelized acceleration lane for northbound traffic entering from Blue Earth County Road 57, improving safety and traffic flow
- Improved lighting at intersections and snow fence
- Improvements to the Rabbit Road bridge over Highway 22
Walking and biking trail
Preparation also began for a future multi-use walking and biking trail connecting Mankato and Saint Peter. Work included grading and construction of a pedestrian underpass near Kasota.
MnDOT received funding to design the trail and purchase property. However, paving between Mankato and Saint Peter and construction of a trail bridge over the Canadian Pacific rail corridor north of Mankato remain unfunded and would be the responsibility of the Minnesota Department of Natural Resources.
