WIS 100 (108th St.) Resurfacing - Milwaukee County


WIS 100: I-43 to the Hank Aaron State Trail in the cities of West Allis and Greenfield


The roadway was last rehabilitated in 1999 and the pavement is in poor condition. The proposed project will restore the condition of the pavement and implement upgrades to the signals to provide more efficient flow of traffic and improved safety at major intersections. In addition, curb ramp and bus stop improvements will make the corridor more accessible for all users.​

Project details

  • Remove existing asphalt layer, base patch underlying concrete pavement, and resurface with new asphalt.
  • Replace traffic signals at Layton Avenue, Oklahoma Avenue, National Avenue, Cleveland Avenue and Lincoln Avenue.
  • Reconstruct curb ramps at various locations to meet current Americans with Disabilities Act (ADA) Standards.
  • Replace asphalt overlay on driveways that were previously overlaid. 


Construction is anticipated to start in mid-summer 2020.

Traffic Impacts

  • During construction, various median openings, intersections, and driveways will need to be temporarily closed. 
  • There will be no changes to access or driveways when construction is complete.​
Staging highlights

  • All work will occur in the existing highway right of way. 
  • WIS 100 will remain open to traffic during construction.
  • WIS 100 will maintain two lanes in each direction during a.m. and p.m. peak hours.
  • Traffic will be reduced to one lane in each direction during evening hours.
  • ​Short term overnight closures/detours will be needed for paving.
