Overview of Project

Bridge maintenance improvements on the US 20 Bridge (Julien Dubuque) over the Mississippi River in Dubuque will involve detouring traffic.
 

The detour uses US 20 in Dubuque to the US-61/151 Iowa-Wisconsin Bridge crossing. Once in Wisconsin, traffic will use Wisconsin Highways 11/35 to Illinois Highway 35 to return to US 20 in East Dubuque.
