Highway 200 detour between Mahnomen and Roy Lake to be removed Friday: Project is still ongoing and remaining work will be done under traffic

N1312P17009HThe detour on Highway 200 between Mahnomen and Roy Lake is scheduled to be removed by the end of the day Friday, Sept. 2.

Phase three of the project begins with the removal of the detour, and the remaining work will be done under traffic. A pilot car and flaggers will control traffic and motorists should plan for daily lane closures in the area where crews are working. It is expected to last until October.

Knife River Materials is the contractor for the $5.5 million project. The work will reduce the risk of flooding and ensure a smoother and safer roadway on 20 miles of Highway 200.
