Road construction season is back in full swing this summer.

People driving along Highway 63 between the Iowa border and Spring Valley will encounter a detour beginning Monday as concrete road repair work begins, according to the Minnesota Department of Transportation.

The $3.6 million project by prime contractor PCI Roads will involve concrete pavement repairs, shoulder replacement, repairs to a bridge and culvert work along the 13-mile stretch south of Spring Valley. The work is expected to be completed by early July.

There will be a detour during the duration of the project. The northbound detour route is Highway 56 west from the Iowa border through LeRoy, Minnesota, and then Mower County Road 14 north to Highway 16 east until it connects with Highway 63 west of Spring Valley. The detour is in reverse for southbound traffic.
