  • As of March 24, C.S. McCrossan Construction, Inc. began occasionally starting work at 6 a.m. on the weekdays and at 7 a.m. on Saturdays. These extra hours will continue through November 2014. Note: pile driving will not begin before 7 a.m. After the unseasonably cold and snowy winter, crews will need the extra hours and Saturdays to complete the project on time. The noise will be from heavy construction equipment, trucks and excavators.
  • Hwy 7 traffic has switched over to the bypass and the Lake Street exit off of Hwy 7 is closed indefinitely. Map

Current Status
Work on the Highway 7 & Louisiana Avenue Interchange project is underway. The contractor has completed clearing and grubbing of areas adjacent to the roadway and the removal of pavement from the shoulder areas. During the initial phase of the construction over the remaining summer months, through traffic on Highway 7 and Louisiana Avenue should remain largely unaffected. Much of the summer construction will include constructing a bypass for Highway 7 (to shift traffic to the south) and perform soil correction work in order to allow construction of the new improvements later in the fall.

Project Description
The project includes the construction of a grade-separated interchange at the Trunk Highway 7/Louisiana Avenue intersection in order to improve access, safety and operations for a number of modes of transportation including vehicle, pedestrian, and bicycle modes, transit and freight flow. The proposed project consists of a tight diamond interchange configuration with roundabouts along Louisiana Avenue for traffic control at the Lake Street and Walker Street intersections.

The City of St. Louis Park initiated a study for a new grade separated interchange at the intersection of Highway 7 and Louisiana Avenue in January 2009. The city and its partners, in conjunction with consultant, Short Elliot Hendrickson Inc. (SEH), developed a preferred concept design for a new interchange through an extensive public participation process. The new interchange will place a Highway 7 bridge over Louisiana Avenue.

Construction began summer of 2013 and will be substantially completed by the end of 2014.

Other Elements of the Project:

  • Reconfigure West Lake Street and Walker Street
  • Add pedestrian and bicycle upgrades
  • Add artistic elements such as lighting and other architectural features to the project

Business Outreach
The City of St. Louis Park is committed, along with its partners, to working with neighborhood businesses throughout the project. MnDOT and the City of St. Louis Park will work directly with affected businesses on disruptions, signage, detours, marketing and more.
