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 will be the lead agency for the West Waukesha Bypass study. Waukesha County, following Wisconsin Department of Transportation and Federal Highway Administration protocol, will lead preparation of an Environmental Impact Statement (EIS) for this project. The EIS will be prepared to comply with the National Environmental Policy Act. The EIS will evaluate alternatives for providing a north-south arterial highway between I-94 and WIS 59 and will also evaluate doing nothing. An EIS documents why the project is needed, alternatives considered, and the impacts of the different alternatives. For more information about Environmental Impact Statements and the EIS process please see the FHWA website.

Schedule

The study is scheduled to culminate in 2014 with a decision by the Federal Highway Administration on whether to build the bypass and, if so, where to build it. If approved, construction is tentatively planned to begin in 2015 north of Summit Avenue and 2015 or 2016 south of Summit Avenue.

Latest News

Engineering surveys will be conducted by survey crews beginning the week of June 9th, and continuing throughout the months of June & July. The survey will include collecting topographic information and setting vertical and horizontal control points. It may be necessary for our survey crews to enter private property, and we ask for your cooperation so that we may obtain accurate information. The survey will be performed by Kapur and Associates under contract by the Waukesha County Department of Public Works.

Waukesha County is working on the Final Environmental Impact Statement for the West Waukesha Bypass study. The Final EIS will document the results of the November 2012 public hearing, comments received during the 45-day comment period that ended in December 2012, any changes to the alternatives that have occurred since the Draft EIS was approved, and reasons why the Pebble Creek West Alternative was selected as the preferred alternative. Waukesha County is working with the DNR, Corps of Engineers and US EPA to obtain their concurrence on the preferred alternative.

The Final EIS will also include new information on groundwater in the Pebble Creek corridor near Sunset Drive based on groundwater monitoring performed in winter and spring 2013. Based on this information, the Pebble Creek Alternatives have been modified slightly to reduce potential groundwater impacts.

After the Final EIS is approved by the Wisconsin Department of Transportation and the Federal Highway Administration it will be made available for public and agency review.

Public Involvement

During the study process, the public will have numerous opportunities to provide comments on the project. A public hearing was held at Waukesha North High School on November 13, 2012. The public is also encouraged to contact Waukesha County project manager Gary Evans with any comments or questions regarding the study. CH2M HILL was selected to assist Waukesha County with completing the EIS. Charlie Webb is the project manager for CH2M HILL and may also be contacted with project-related comments and questions.
