The Leo Frigo I-43 bridge that crosses the Fox River in Green Bay, Wisconsin has been closed since yesterday morning due to the center portion of the bridge 'sagging' more than two feet, according to the Wisconsin Department of Transportation.
The Milwaukee Journal-Sentinel has more information on why the bridge started sagging:
The likely culprit is the settling of Pier 22, a support pillar that is on the east approach to the bridge, Gottlieb said.The story goes on to say that the state does not believe that the bridge is any danger of collapsing.
The pier settled a little over two feet, and the state DOT will continue taking periodic measurements to see if it's continuing to settle or if any other piers are affected, he said.
The bridge, formerly known as the Tower Drive bridge, will remain closed as inspections continue, said Kim Rudat, regional communication manager for the state Department of Transportation's northeast region.
Wisconsin has 1,151 structurally deficient bridges according to Transportation for America. The Leo Frigo Bridge is not listed as structurally deficient on their website.
It's always worth noting that Green Bay's US Representative Reid Ribble (R-WI) voted in favor of sequestration, saying that the legislation didn't go far enough in cutting away at the Federal government. Sequestration cut over $2 billion from the Department of Transportation budget, including removing over $101 million from highway maintenance.
