GREEN BAY - The Department of Transportation says corrosion is the likely cause of the Leo Frigo Bridge failure on Sept. 25. Pier 22 sank nearly two feet causing the road surface to sag.
Police closed the bridge and the DOT says it will remain shut down indefinitely.
Crews reportedly found the corrosion by digging eight feet below the ground. Engineers say the bottom of the support piling buckled. There are also signs of corrosion on other piers. Experts say the corrosion was caused by the soil and changes in the water table near the bridge.
The DOT says it believes the structure of the bridge appears to be in good shape and they do not believe it is in danger of collapsing.
It is still not known how long it will take the fix the problem or how long the Leo Frigo Bridge will be closed.
