A formal groundbreaking ceremony will be held Tuesday afternoon in Stillwater for the St. Croix Bridge project. Work is already underway on the project, which will cost between $580 million and $676 million.
The new bridge will span the St. Croix between Oak Park Heights in Minnesota and St. Joseph in Wisconsin, and replace the 80-year-old Stillwater Lift Bridge.
Elected officials from Minnesota and Wisconsin are scheduled to speak at the ceremony at Lowell Park in Stillwater.
"We are just looking for a salutatory event just to say that everything is underway," said Minnesota Department of Transportation spokeswoman Mary McFarland Brooks.
MnDOT is also establishing a no-wake zone for boaters near the bridge site, which will remain in effect for four years or until the bridge is complete.
