Overnight closure of US 45 southbound at I-41/US 45 split


Sept. 16, 2016

The Wisconsin Department of Transportation (WisDOT) is scheduled to perform pavement marking on US 45 southbound in Washington County. To facilitate this work, a full closure of US 45 southbound, at the I-41/US 45 merge, will be required.

The closure of US 45 southbound is scheduled to begin Friday, September 16 from 8 p.m. until 8 a.m. the following morning. During this time, I-41 southbound approaching the merge will remain open. I-41/US 45 southbound at the split will be restricted to one lane.


       For southbound US 45 traffic: Exit at westbound WIS 145. Continue west on WIS 145 to connect with the entrance ramp for southbound I-41. Interstate 41 will merge with US 45.

Safety to the traveling public is of the utmost priority. The safest way to perform this work is by fully closing this segment of the US 45 roadway. If weather conditions prohibit this work, the work will be scheduled for the evening of Saturday, September 17 from 8 p.m. to 8 a.m.

The aforementioned activity is part of the I-41/US 45 Rehabilitation Project. More information can be found on 511 Wisconsin at
