New, temporary weight restrictions go into effect Thursday for heavy trucks using the Stillwater lift bridge across the St. Croix River.
Inspectors from the Minnesota Department of Transportation found components of the bridge had significant corrosion as part of a routine inspection, according to MnDOT bridge engineer Nancy Daubenberger.
"Corrosion of the steel is such where enough has fallen away that we need to reassess the load-carrying capacity of the bridge," she said. "That is routinely done with these inspections.
Daubenberger says the change in the load rating will reduce the weight of trucks and other heavy loads that can cross the bridge until repairs can be made beginning this week. The repairs could take up to 10 days to complete.
The bridge remains safe for daily traffic, she said, and adds that it is scheduled for major repairs next year.
