St. Croix Crossing final work and mitigation

Although the Hwy 36 St. Croix river crossing opened to traffic on Aug. 2, 2017, additional work remains to complete the project.

Work includes:
  • Final cleanup and landscaping
  • Rehabilitation and conversion of Stillwater Lift bridge to bicycle/pedestrian traffic and to serve boat traffic. When completed, 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. St. Croix 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

Stillwater Lift Bridge Project

Bridge closure
August 2017 through winter 2019-2020

With the new St. Croix Crossing bridge opened to traffic, the historic Stillwater Lift Bridge conversion project has begun. The Lift Bridge is now closed to ALL traffic. Marine traffic is now traveling through an opening in the bridge.

The Lift bridge, spanning the St. Croix River, will be converted to a bicycle/pedestrian crossing and will also become part of a five-mile “loop trail” system connecting the new river bridge with the historic bridge. The Lift Bridge will continue to operate to allow boat navigation beneath.
