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


July 13, 2016

The Wisconsin Department of Transportation (WisDOT) is scheduled to perform milling and paving work at the I-41/US 45 split in Washington County. To facilitate this work, a full closure of US 45 southbound, but not I-41, will be required.

The closure of US 45 is scheduled to begin Friday, July 15 from 8 p.m. to 8 a.m. During this time, the WIS 145 entrance ramp to US 45 southbound is scheduled to be closed. A single lane closure of I-41 southbound, approaching the split, is also scheduled.


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 at the split.

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 take place later this month.

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