Stearns County says the roundabout will be at the intersection of County Road 133 and 19th Avenue South. Detours around the new roundabout roadwork include 2 1/2 Street North, Pine Cone Road, County Road 120 and County Road 4.

Construction is scheduled to be completed by early September, weather permitting.
