Emergency repairs will be made to the bridge along County Road 1 in southeast Rock County.
Ice flow this spring damaged the bridge’s wood pilings, allowing a three-inch sag to develop on the bridge deck.
Repairs are estimated at $52,500.
Since state officials deemed the repairs as an emergency, the county is able to tap into the Federal Highway Emergency Fund to pay for the completed work.
Commissioners agreed May 7 to repair the bridge over Kanaranzi Creek with plans to replace the structure in the future.
Once a contractor has been secured, repairs will take almost three months to complete.
The repairs involve the installation of new steel pilings and transfer girders under the existing structure, according to County Engineer Mark Sehr.
Replacement of the bridge is expected to take place in the next five years.
Until the repairs are completed, the bridge remains open. Traffic is restricted to one lane with a 20,000-pound weight limit.
Once repairs are complete, weights will return to previous load limits.
The one-lane restriction began April 9.
No semitrailer traffic is allowed on the bridge until repairs are completed. The damaged bridge continues to be monitored twice a week by highway officials.
“If we notice anymore movement, we will close it down,” Sehr said.
