Project location

WIS 19/WIS 113 Intersection, Town of Westport, Dane County

Project overview

The proposed safety project would replace the current intersections of WIS 19/WIS 113 and County I with a modern multi-lane roundabout. Due to the high rate of crashes at the location, this project qualified for Highway Safety Improvement Program (HSIP) funding. The proposed design reduces the number of intersections from three to one. The proposed improvement will provide safer operations to motorists and reduce congestion at the intersection. A few key features of the proposed roundabout are listed below:

  • Dual-lane entries provided on all approaches except County I
  • The westbound approach on WIS 19 would be expanded from a single lane to two lanes, and the northbound and eastbound approaches would remain as two lanes approaching the intersection
  • A full bypass lane would be provided for eastbound and northbound right turn movements
  • Project overview


  • Summer 2018 - Construction anticipated

Traffic impacts/detours

The roundabout will be constructed in stages with WIS 19 and WIS 113 open during construction. County I will need to be closed for some time to complete the proposed work. 

More information on this project will be provided as the design process continues.
