Rehabilitation project on I-41/US 45 in Washington County to resume
Traffic impacts may occur during off-peak times

 

March 8, 2016

Beginning Monday, March 14, the Wisconsin Department of Transportation (WisDOT) is scheduled to recommence major work on a rehabilitation project on I-41/US 45. The project limits extend from the Washington/Waukesha County Line (County Q) to the US 41/45 split, in Washington County, a distance of roughly six-and-a-half miles.
 
During peak hours, all travel lanes on the freeway mainline will remain open. In off-peak hours, single and double lane closures will be in effect, which may cause congestion.
 
The project began in August 2015. During the winter months, operations suspended except for traffic signal work at the County Q and Lannon Road interchanges. The contractor, Payne & Dolan, is planning on completing the project in fall of 2016. The schedule is weather dependent and subject to change.
 
 
2015 work
  • Completed reconstruction of the southbound bridge at the I-41/US 45 split
  • Finished base patching of corridor
  • Completed realignment and widening of ramps at the County Q and Lannon interchanges
  • Began signal work at the County Q and Lannon Road interchanges
 
2016 work
  • Milling and overlaying, along with installing new asphalt
  • Upgrading the cable guard system
  • Installing a high friction surface treatment from Friedstadt Road to Holy Hill Road
  • Building up the curve banking from Friedstadt Road to Holy Hill Road
  • Adding lighting at the Lannon Road Interchange
  • Completing signal work at the County Q and Lannon Road interchanges
 
The project will also provide upgrades to the Freeway Traffic Management System, with new fiber optic cables and microwave detectors, allowing WisDOT to better compute travel times used by the public via 511 Wisconsin.
