Bridge maintenance required on two structures in southeast region
Temporary closures needed to facilitate work


April 9, 2018

The Wisconsin Department of Transportation is advising motorists of several closures that will be happening in southeastern Wisconsin over the next several weeks. Maintenance crews will be repairing bridge girders on the structure carrying Racine Avenue (County Y) over I-43 northbound in Waukesha County, as well as the I-43 southbound structure over US 12 in Walworth County. This work consists of heat-straightening applications to repair damaged steel girders which will help restore the structural integrity of the bridges.

I-43 Southbound Bridge over US 12, Walworth County

Closure: Loop exit ramp from I-43 southbound to US 12 eastbound, as well as the collector-distributor lanes on eastbound US 12 at the bridge. Travel lanes on eastbound US 12 are to remain open.
Detour: These closures affect access to the County NN Interchange and US 12 eastbound. Motorists should continue south along I-43 and use the nearby WIS 67 (Lincoln Street) interchange to return to I-43 northbound to access US 12 eastbound and County NN.
Approximate Closure Duration: April 12 April 22

Racine Avenue (County Y) Bridge over I-43 Northbound, Waukesha County

Closure: Full closure of I-43 northbound at the bridge during nighttime hours (9pm-5am)
Detour: Motorists are to utilize the Racine Avenue off-ramp, and navigate straight through the roundabout to re-enter the Racine Avenue on-ramp continuing to I-43 northbound.
Approximate Closure Duration: Nightly closures from April 16 April 29

Both projects are required maintenance due to previous bridge hits from over-height vehicles. This specialized work also requires painting, and is heavily dependent on weather and is subject to change.
