Motorists in Renville County will encounter a daylong detour on Highway 19 between Morton and Franklin this Thursday. The detour follows Highway 71 to County Road 2 and County Road 5, then Highway 19. The detour is needed for the University of Minnesota to conduct load testing research on the pre-stressed concrete beam bridges in the area. Two other bridges across the state will also be tested. Mn/DOT urges motorists to always drive with caution, slow down in work zones, and never enter a road blocked with barriers or cones.
