Work set to begin on sagging Green Bay bridge

GREEN BAY, Wis. — Workers are set to begin building a temporary steel frame Monday to support a Green Bay bridge that had to be closed last month after a portion developed a deep dip in the pavement.
Investigators determined that the problem arose when pilings beneath the pier corroded and buckled, causing a support pier of the Leo Frigo Memorial Bridge to sink about 2 feet. So the state Department of Transportation hired a construction company to build a structure to help keep the bridge stable.
Crews will erect a pair of steel towers beneath the bridge on either side of the sagging Pier 22. The temporary steel frame is intended to prevent further sagging while investigators diagnose and correct the problem.
The temporary fix will cost $1.5 million, but the full amount is expected to be covered by the federal Emergency Relief Program. Permanent repairs could cost as much as $50 million, although that figure could fluctuate as transportation officials develop a final repair plan.
Officials said the steel frame should be complete in four to six weeks.
The bridge had been carrying 40,000 vehicles per day across the Fox River on Interstate 43. No timeframe has been announced for when the bridge might reopen.
