MINNEAPOLIS (WCCO) — The Minnesota Department Of Transportation says parts of Highway 67 near Granite Falls will remain closed due to an expanding fault line on the road.

The road collapse is located between County Road B1 and 600th Street near the Upper Sioux Agency State Park entrance. The road has been closed since March.

According to MnDOT, the ground is moving about one inch per day.

An engineer is testing the ground to learn what’s causing the road to split.

In the meantime, a detour has been set up to get to the main entrance of the Yellow Medicine Campground.

According to MnDOT this closure and detour is expected until Fall 2019.
