SARTELL -- Construction crews will be preparing a south Sartell intersection for a major reconstruction project this week.

Crews will begin staging work at the intersection of Heritage Drive and Stearns County Road 1 for a new roundabout intersection there.

Stearns County Engineer Jodi Teich says the traffic impacts will begin after the 4th of July holiday. The Heritage Drive connection to the River Road will be closed starting July 5th.

In early August, Teich says the River Road will be closed to traffic prompting a lengthy detour around the work zone via County Road 120, to Pinecone Road, to 2nd Street South.

The new roundabout should be open by the end of October.

In a separate project, MnDOT continues work on improving Highway 15 in that area. That project should be completed by the end of August.
