About this project

The Hwy 36 St. Croix river crossing opened to traffic on Aug. 2, 2017.

Work included:

  • Final cleanup and landscaping
  • Rehabilitation and conversion of Stillwater Lift bridge to bicycle/pedestrian traffic and to serve boat traffic. When completed in late spring 2020, the lift bridge will be part of the new 4.7 mile Loop Trail that also includes the new St. Croix River crossing.
  • The Loop Trail in Wisconsin is now complete and ownership of the trail has transferred to St. Croix County. The county is now responsible for management of the Wisconsin portion of the trail.
  • Growth Management and Riverway MOU mitigation items
  • Minnesota Dept. of Natural Resources’ boat access. The DNR is requesting approval and designing a new boat landing next to the St. Croix River Crossing bridge in Minnesota. For more information, contact Kent Skaar, Minn. DNR at 651-259-5646 or
