If you would like to see an overview of the road construction leading into Prairie du Chien watch the attached video. The DOT is turning U.S. Hwy 18, from the Wisconsin River bridge to the entrance of Wal Mart, from a 2 lane road into a 4 lane divided highway. It's a 3.2 mile stretch.
The work has begun, and will be almost, but not quite, finished by November. The construction will restart in the spring of 2017 for an additional couple of months. The DOT plans to maintain traffic throughout the construction period. mwnews.net
