ST. CLOUD -- A popular commuter route in St. Cloud and Sartell will effectively be closed starting Monday.

Stearns County Road 120 will be closed at the Highway 15 intersection for a month.

Workers will be building temporary ramps to handle traffic while work on the diverging diamond interchange is underway.

There will be two detours for motorists to access Sartell businesses along Highway 15. One detour is via Stearns County Road 1 to access Epic Center. The other is a temporary intersection to access the medical campus in Sartell.

Traffic on Highway 15 won't be detoured, but delays will be common.

The intersection is expected to re-open to traffic in late-May.
