After I-90 had been open for a few years, Wisconsin DOT wanted to put in a state entry rest area and tourist information center. The first dry land after entering the state from Minnesota was on the western edge of French Island. While there was enough land for the rest area and the exit road, there was no place to put the entrance road. As a result, the I-90 causeway near French Slough was made wider, and a small bridge was put in place parallel to the existing two I-90 bridges over French Slough. That solved the entrance road issue in a very clean and safe manner.

The photo above is looking north from the rest area nature trail towards the rest area bridge. The photo below is taken just after exiting I-90 Eastbound and prior to crossing the bridge or entering the rest area.
