Dubuque–Wisconsin Bridge

The Dubuque-Wisconsin Bridge is a steel arch bridge spanning the Mississippi River and connecting Iowa with Wisconsin. The structure features four traffic lanes and carries US Highway 61 across the water with a distinctive arched design.

The bridge opened in 1982 and replaced an older crossing to handle increased traffic between the two states. Its construction in the early 1980s involved significant engineering challenges across the river valley.

During construction in 1980, workers discovered a Native American burial site at the Wisconsin bluff, requiring ceremonial sanctification by a Winnebago medicine man.

The bridge carries US Highway 61 with steady traffic throughout the day. Pedestrians and cyclists should use caution or seek alternate routes, as the structure is primarily designed for motor vehicles.

Workers discovered a significant archaeological site during construction in the early 1980s. This finding required special ceremonial recognition before work could continue.
