Purpose and Need

In April 2009, a Memorandum of Understanding was signed by Waukesha County, the City of Waukesha, the Town of Waukesha, and WisDOT, identifying the local, county, and state responsibilities for building the West Waukesha Bypass. The intent of the project is to provide a roadway facility on the west side of the City of Waukesha to safely and efficiently accommodate existing and future traffic volumes. To better accommodate the flow of traffic, segments of the existing roadway will be expanded from two lanes to four. This project will provide a link around the city by connecting I-94 and WIS 59.
