Westside Drive remains open

As a result of concerns from the residents of St. Louis Park, we will postpone closing Westside Drive until further notice. The exit will be signed local businesses only, but there will not be barriers that prevent people from continuing south on the frontage road.

The closure was a decision the city of St. Louis Park and MnDOT made to deter motorists from using local streets to bypass slow moving traffic on Hwy 100 and to minimize congestion at the Hwy 7/Wooddale interchange.

We are committed to identifying ways to reduce the traffic in the neighborhoods being generated by the Hwy 100 project.

Overnight noise

  • Because we will be making the traffic switches overnight residents should expect to hear typical construction noises (trucks moving and hauling) overnight through fall 2016.
