Hwy 37 roundabout construction to start June 20

DULUTH, Minn. –  On Monday, June 20, construction on the roundabout at the intersection of Hwy 37 and St. Louis County Road 7 will begin.

Hwy 37 traffic will be switched to the westbound shoulder and driving lane.  County Road 7 south of Hwy 37 will be closed at Hwy 37 to traffic and will be detoured.  Traffic north of Hwy 37 on County Road 7 will be shifted to accommodate reconstruction of the lanes north of Hwy 37 at this time.  In the future, County Road 7 north of Hwy 37 will be closed to traffic and detoured. Motorists should expect a 35 MPH speed limit and 12’ driving lanes on Hwy 37.
