Wisconsin transportation officials have a plan in place to fix an interstate bridge in Green Bay that sagged in late September. The state DOT hopes the hired contractor will complete the repairs by the end of January on the Leo Frigo Bridge that carries Interstate 43 across the Fox River.
Investigators are still trying to figure out exactly why a pier on the east side of the bridge settled on Sept. 25 and caused a 400 foot cross-section of the bridge to sag.
Wisconsin Department of Transportation spokesman Kim Rudat says the pier that settled, known as Pier 22, is structurally fine even though it is now a few feet lower than the other bridge piers. The repair will include putting a cap on top of Pier 22 to bring the repaired bridge deck in line with the other piers.
“While the rest of the piers will all be at a certain height, Pier 22 will for the rest of its service life be two feet below the rest with a bigger cap on top of it holding up the bridge,” Rudat told “Land Line Now” on Sirius XM radio.
WISDOT built in some incentives and disincentives for the contractor to finish the project by the end of January, Rudat said.
“This is an unusual situation. This is a bit of an anomaly, so it might go a little longer,” he said. “We’re just assuring people we expect to have it open by the end of January. This contract really has no days off in it – nothing that could do with weather. Literally, the only day we’re giving them off is Christmas Day.”
I-43 traffic is primarily using Wisconsin Route 172 to cross the Fox River.
The Leo Frigo Bridge was built in 1980. According to WISDOT, the bridge was not considered deficient as of its last inspection in August 2012.
