Army Corps Grants MnDOT Permits to Complete Construction of St. Croix River Crossing

The U.S. Army Corps of Engineers has issued the Minnesota Department of Transportation the permits needed to complete construction of the new St. Croix River Crossing.

The Corps’ permit includes two authorizations under the Rivers and Harbors Act’s Section 10 and the Clean Water Act’s Section 404.

Both authorizations were required due to the construction involving work within the St. Croix River. Now that the application has been approved, MnDOT can start the bid-letting process for construction work.

The permits authorize MnDOT to construct:

• Bridge support piers in the St. Croix River and its adjacent wetlands;
• Bridge approach in wetlands on the Minnesota side of the river;
• A storm water pond in wetlands in Minnesota;
• Associated road and interchange improvements in wetlands in Minnesota;
• A storm water outfall structure on the Wisconsin side of the river.

The permit also authorizes MnDOT to remove an unused barge unloader facility from the Allen S. King Plant—and redistribute aggregate fill from within the facility cells on the river bottom.
