First of two detours now in effect for Highway 16

The first detour on Minnesota Highway 16 went into effect Monday morning, diverting motorists at Spring Valley to Highway 63 as part of a paving and culvert replacement project this summer from Dexter to Spring Valley, according to the Minnesota Department of Transportation.

The detour from Spring Valley to U.S. Highway 63 is expected to last four weeks. It will direct motorists on Highway 16 in Spring Valley to Fillmore County Road 8 to Highway 63 back to Highway 16.

A second detour starting after work on the first section is completed will last two months. It will direct motorists on Highway 16 at Dexter to Mower County Road 7 to Mower County Road 2 to Highway 63.

Rochester Sand and Gravel, a MnDOT contractor, is scheduled to repave approximately 15 miles of Highway 16 from Spring Valley to Grand Meadow to Dexter. The project should be complete by mid-October.

Detours will be in effect during two stages of the project to allow for culvert replacements. Local traffic will be able to reach businesses and residences via side roads to Highway 16. Motorists will encounter single-lane traffic and brief closures of intersections later during the paving operation.
