USH 18, Prairie du Chein, Crawford County, WI

Westbrook was contracted for the design of 1.4 miles of reconstruction of USH 18 just South of the City of Prairie du Chein, Wisconsin. The existing roadway was a two lane rural highway located in a newly developed commercial area. Westbrook’s objective when designing the project was to increase the capacity of the roadway.

Our design team accomplished increasing the capacity of the road by developing a four-lane urban roadway design that incorporated a left turn lane in the median. We also relocated a side street so the appropriate spacing between traffic signals at two adjacent intersections could be achieved. This helped to regulate the traffic flow and spacing. Traffic signals were installed at three intersections as part of the project. 

The new design also included adding storm sewer and two retention ponds to replace the large flat ditches along the existing roadway. A ten-foot wide bike/pedestrian path was added on the south side of the roadway. This was incorporated into the project to provide a safe place for non-vehicular transportation to access businesses along the highway. Street lighting was also added along the roadway to increase safety.
