Highway 81 Closed Due to Collapse of Diversion Area Project in Cass County
What happened
A section of the Fargo-Moorhead Diversion Area Project collapsed, impacting operations in Cass County, North Dakota. The failure involved a section of the road embankment that started as a 1-inch crack and escalated into a 4-foot elevation drop within 72 hours. The road closure, which began on September 1st, was due to the infrastructure failure. The cause was attributed to soil moisture issues in the clay used for the construction.
