Project location

WIS 19 and Westmount Drive intersection, Sun Prairie - Dane County

Project overview

The Wisconsin Department of Transportation (WisDOT) is proposing an intersection safety improvement project along WIS 19 and Westmount Drive intersection in Sun Prairie in Dane County.

The intersection WIS 19 and Westmount Drive has a history of rear-end crashes due to stopped traffic turning left in the through lanes of WIS 19. From 2014 - 2018, there were twelve crashes, and eleven involved stopped traffic turning left on WIS 19.

The single-lane roundabout alternative was chosen in spring 2023. This alternative addresses the purpose and need of the project by improving the left turning movements on all legs of the intersection, providing natural traffic calming from the normal operations of a roundabout, and provides pedestrian crossings of WIS 19.


Traffic impacts/detours

Staged construction will allow at least one lane of WIS 19 to remain open in each direction
