County Road 1 (Old Highway 66) between County Road 9 and County Road 90 will be closed for reconstruction beginning Monday, July 26, 2021. Drivers should expect this portion of the road to be closed until fall and are encouraged to find alternate routes. The posted detour route will be via County Road 90, County Road 16 and County Road 35.


This 2.8-mile project is the final phase of the Old Highway 66 turnback project from Good Thunder to Mankato. Due to the complexity and magnitude of work, the project will be completed over two construction seasons.
