Overview
WisDOT is proposing to rehabilitate approximately 3.6 miles of WIS 16 in the towns of Oconomowoc and Nashotah in Waukesha County. As part of this project, the Wisconsin Avenue bridge over the Oconomowoc River is also proposed for replacement.
Important Update 10/17/2024
The Wisconsin Avenue frontage road bridge over the Oconomowoc River is currently closed. Motorists are encouraged to use WIS 16 to get around the closure.
Access to local businesses and residents will be maintained during the closure.
To reopen the bridge in a safe and timely manner, WisDOT is developing an expedited construction plan to replace the bridge in 2025.
Project Details
This project will now be completed in two stages.
Stage 1. 2025:
- Replace the Wisconsin Avenue bridge over the Oconomowoc River.
- Resurface Wisconsin Avenue from WIS 67 to Brown Street.
Stage 2. This portion of the project is scheduled for 2027.
- Concrete repair and asphalt overlay on WIS 16 from WIS 67 to the Oconomowoc River
- Concrete pavement rehabilitation with mill and overlay of asphalt shoulders on WIS 16 from the Oconomowoc River to County P
- Maintenance on several drainage culverts and inlets
- Concrete pavement rehabilitation with mill and overlay of asphalt shoulders on all ramps at the interchanges of WIS 67, Brown Street, and Sawyer Road
Traffic Impacts
Stage 1: The Wisconsin Avenue frontage road bridge over the Oconomowoc River will remain closed until it is replaced. Access to local businesses will be maintained during construction. The nearby Oconomowoc River kayak launch will remain open until construction, then reopen when the bridge work is completed.
Stage 2: WIS 16 will remain open to traffic during construction. Traffic will be staged with one lane open in each direction of travel. Ramp and frontage road detours may be necessary at some times.
The proposed traffic plan is preliminary and is subject to change.
