Highway 67 at Granite Falls will remain closed
Highway 67 southeast of Granite Falls has been closed between the Upper Sioux Agency State Park entrance and 600th Street, just west of the Yellow Medicine River Bridge, since April 4, 2019.
Portions of the roadway have shifted, causing several significant drops in the driving lane. The Minnesota Department of Transportation (MnDOT) has barricades in place and motorists are restricted from using the roadway at this location. Groundwater depth and saturation levels are also being monitored.
The embankment has moved at a consistent rate, approximately one inch per day at the main pavement crack. Additional monitoring and slope stability modeling is needed before MnDOT can consider slope stabilization options and a feasibility study for reopening the road.
Therefore, this segment of Highway 67 will remain closed into 2020. Traffic will continue to be routed on Highway 23, Highway 274, and County Road 18 until further notice.
