(Granite Falls MN-) Highway 67 south of Granite Falls remains closed due to a pavement failure, and will likely remain closed for the foreseeable future. Soils Engineer Cody Brand with the Minnesota Department of Transportation says the road developed a huge crack on April 4th near the Upper Sioux Agency State Park...

...Brand says they are studying the nearby slope using drones and geological instruments in 4 locations...

...Brand says while the road failure may have been inevitable, the pavement has lasted for decades until this past Spring when heavy rains saturated the area. The National Weather Service says the past 12 month period is the 4th wettest since 1895. With the proximity of the Minnesota and Yellow Medicine Rivers and all the rain, the soil has become saturated and lost strength. Since April 8th, Brand says there has been an additional 2 feet of movement in the road surface. He says a portion of Highway 67 is still open for those wanting to use a portion of the state park...

...Brand says the detour involves going south on Highway 274 and east on County Road 18 to get back to Highway 67.
