I-43 work could cause problems for drivers

Posted at noon on March 16, 2017

The Brillion News

The state Department of Transportation is reminding drivers that long-term lane closures on I-43 in Brown and Manitowoc counties begin Monday, March 20.

The closures will result in only one lane of travel open to drivers on segments of I-43 in the project work areas. Motorists may experience delays during peak travel times. The closures are part of an I-43 resurfacing and bridge structure project taking place between March 20 and November 2017. Some local roads and I-43 ramps will also close for construction.

Because of the traffic congestion concerns, the State Patrol will be targeting violation in the area where work is scheduled.

The Brown County I-43 resurfacing and bridge overlay project will take place on 10.6 miles of I-43 between Denmark and Bellevue, from State 96 to State  172.

  1. Monday, March 20 to late May: County MM overpass at I-43 CLOSED and detoured for bridge deck replacement. County MM/I-43 ramps will remain open during deck replacement, but motorists will not be able to cross the bridge deck over I-43. Motorists seeking access to U.S. 141/29 from southbound I-43 will be directed to use County JJ/I-43 exit.

Special I-43 work zone law enforcement

The Wisconsin State Patrol will provide special enforcement in the I-43 project work zones to ensure worker and driver safety. Motorists are reminded to obey work zone speed limits. Talking on a mobile device in a work zone (without the aid of a hands-free device) is illegal. Texting and driving is always illegal. Fines double in work zones. Please limit all distractions while driving in a work zone.
