GREEN BAY, WI (WTAQ) - Two towers will be installed next week to keep the Leo Frigo Interstate bridge from sagging any further.
The steel truss towers will placed on both sides of the bridge, extending 55 feet away from the support pier which sunk by two feet early on September 25th -- apparently due to water corrosion.
A week ago, officials said the pier fell by another half-inch. The truss towers will be designed to stabilize the bridge and keep it from sagging further.
The Leo Frigo bridge is located on I-43 over the Fox River. It will stay closed until all repairs are finished.
Lunda Construction of Black River Falls is the lead contractor for the project, which will cost just over $1.5 dollars. It starts Monday, and is expected to be finished by early November.
Federal funds will cover all repair work for the first six months after the incident, and they'll pick up 95 percent after that.
Also, the DOT is installing lateral supports at the tops of four other piers, to protect workers on the bridge.
The DOT says the four piers have not moved at all -- but the supports will keep the piers completely vertical.
Officials say they continue to investigate the condition of the other piers, which will continue into next week.
