DULUTH, Minn. - State transportation officials have closed a stretch of Interstate 35 in Duluth after an inspection found a deteriorating support piling.
The damaged piling is one of 38 that support a low bridge on the southbound lanes of the interstate. Minnesota Department of Transportation (MnDOT) engineer Duane Hill tells the Duluth News Tribun the piling was so corroded they could actually see through it.
Whitney Horky of Duluth told the News Tribune she was concerned because of the short notice.
"I commute that way every day," she said. "I'm thankful that it was caught during inspection instead of something more serious happening."
Repairs are expected to begin Tuesday. Officials expect the southbound lanes to be closed for at least a week or more.
While the corrosion was serious, there was no indication the long, low bridge was near failure, Hill said. Parts of that stretch of freeway received considerable work on the decking and roadway in recent years, but not the support piers, Hill said.
