West Waukesha Bypass Study

In February 2010 Waukesha County began a detailed study of the West Waukesha Bypass between Interstate 94 and WIS 59 on the west side of the City of Waukesha. The transportation improvements are being studied to address growing local and regional traffic volumes, and to enhance traffic flow and safety.

The West Waukesha Bypass has been in county and regional transportation plans for decades. In April 2009, a Memorandum of Understanding (1.34 mb PDF) was signed by Waukesha County, the City of Waukesha, the Town of Waukesha, and WisDOT, identifying the local, county, and state responsibilities for studying and possibly building the West Waukesha Bypass.

The route of the proposed bypass is shown here (998 kb PDF).

Next Steps

Waukesha County completed the West Waukesha Bypass study in January 2015. Waukesha County is now in the preliminary design phase for the entire route and final design has begun for the section of roadway north of Madison Street to Rolling Ridge Drive. The City of Waukesha, Waukesha County and WisDOT are responsible for final design and construction of different segments of the roadway. The City will construct the segment from Rolling Ridge Drive to Northview Road. The County will construct the segment from Northview Road to Summit Avenue. WisDOT will construct the segment from Summit Avenue to WIS 59.


Design will continue through 2016. Construction will begin north of Summit Avenue in 2017 and south of Summit Avenue in late 2017 or 2018. Real estate acquisition began in 2015 throughout the project corridor.
