The County Highway 9 bridge is built on top of the Winnibigoshish Dam. This 1990 structure replaces a 1909 bridge that was rebuilt in 1975.

This is the first of five bridges that cross the Mississippi River where the great river forms the boundary between Cass County and Itasca County. Two of these five river crossings are county roads. Unlike these other two county highway river crossings, on this river crossing, both counties use the same highway number on each side of the county line. In this case, it is Cass county highway 9 on the south side of the river, and Itasca county highway 9 on the north side of the river.

Note the vertical columns sitting on the dam structure that support the bridge. The photo at the top of the page is a view looking north across the length of the bridge deck.

The photo above is a view looking south down the length of the bridge deck. The dam gate mechanisms are located to the right of the bridge. The photo below is the bridge plate.
