Construction planned on Minnesota Highway 91 has gone through several delays already. But road work south of Russell — along with a detour — is now expected to begin Monday, the Minnesota Department of Transportation said.

Starting Aug. 19, traffic on Highway 91 between Russell and U.S. Highway 14 will be detoured, MnDOT said. The detour will last about five weeks. Traffic will be directed west on Highway 14 and north on Highway 23.

The detour is part of a larger construction project covering 45 miles of Highway 91 in Lyon, Murray and Nobles Counties. The project includes replacing bridges and box culverts along the highway, as well as resurfacing, additional lighting at rural intersections, and sidewalk and driveway improvements in Adrian and Lake Wilson.

Highway 91 will also be detoured between Adrian and Lismore in Nobles County, MnDOT said. Traffic will be detoured to Nobles County Roads 35, 15 and 16 for about two weeks.

Construction on Highway 91 is expected to be complete next June, MnDOT said.
