SARTELL -- Construction crews are closing a busy Sartell street for a day while crews perform some underground work.

Stearns County Road 1, also known as Riverside Avenue will be closed between Highway 15 and Heritage Drive for approximately 24 hours starting Monday afternoon. There will be a detour posted.

The work is part of the improvement project to build a roundabout at Heritage Drive and widen County Road 1 in that area.
