The eastbound traffic detour west of Cass Lake begins today.
MnDOT says that the detour will use Hubbard County Roads 45 and 9, and Cass County Road 22, for eastbound drivers on Highway 2.
Westbound traffic will be reduced to one lane.
Crews will be resurfacing Highway 2 from two miles east of Hubbard 46 to Highway 371 in Cass Lake.
The detour is expected to last one week.
Knife River is the contractor for the $2.5 million project.
