Port Washington, WI – Drivers across Ozaukee County are facing major delays today after multiple crashes shut down both directions of I-43, prompting detours and extended closures expected to last for several hours.
According to the Ozaukee County Sheriff’s Office, the first crash occurred on I-43 southbound at CTH LL in the Town of Port Washington, where a semi jackknifed and blocked both lanes. Southbound I-43 is fully closed, with traffic diverted onto CTH D in Belgium.
A second crash was reported on I-43 northbound at STH 33 in the Town of Saukville. Deputies say a southbound semi allegedly lost control, crossed the median and struck multiple vehicles in the northbound lanes. I-43 northbound is closed at the overpass, and traffic is being diverted off at STH 33.
The Sheriff’s Office reports that the interstate will remain closed in these sections for several hours while first responders work the scenes and crews clear debris. Drivers should expect long delays through midday. Updates will be released as lanes reopen.
Road conditions across Ozaukee County have deteriorated quickly due to icy pavement, strong winds, snow, and falling temperatures. Officials urge drivers to avoid travel if possible and to reduce speed significantly if they must be on the road.
Residents in Port Washington, Saukville, and the surrounding Milwaukee metro corridor are encouraged to monitor travel advisories and plan detours ahead of time.
