The Prairie du Chien river crossing crosses three river channels. The final channel crossing on the east side from Saint Feriole Island to the Wisconsin mainland is divided between two bridges, the east bound Iowa Street Bridge, and the westbound Wisconsin Street Bridge.

The two approach bridges are nearly identical using concrete girders and a concrete deck. The only real differences are that the Wisconsin Street Bridge is slightly longer, and it has a bit of a slant, while the Iowa Street Bridge is just slightly shorter but is built relatively level.

The Wisconsin Welcome Center is located on the east end and between these two bridges. That provides a safe and convenient place to park and photograph these two bridges.
