Update 1/10/25 @ 5:30 p.m. – 511wi.gov is no longer showing the freeway as being closed.
A press release, shown below, from Rock County Public Works announced a road closure on I-39/90 due to a crash. Though the release does not indicate whether both sides of the interstate are closed, 511wi.gov indicates that it is only the southbound traffic that is detoured. Per below, it is expected that the detour will continue through Friday evening’s commute.
“On January 10, 2025, at approximately 11:47 a.m. a significant crash occurred on I-39/90 near mile marker 182 eastbound. The investigation showed the accident involved a semi tractor trailer and a Rock County Department of Public Works plow. At the time of the incident, the plow was clearing snow on the inside median as part of winter maintenance efforts following this morning’s snow event. The semi tractor trailer struck the plow on the rear passenger side. The driver of the plow reported being uninjured but is being evaluated at a local hospital.
Traffic on I-39/90 is currently being re-routed utilizing STH 11, CTH G and CTH BT. The anticipated length of the closure is unknown but will likely extend into the evening commute. The Wisconsin State Patrol is currently on scene and will be investigating this incident. County resources are supporting the incident response.”
