The morning commute on Interstate 90 turned tragic Wednesday when a 32-year-old DeForest woman was fatally injured after her car collided with a semitruck in the town of Windsor. The crash happened around 6:50 a.m. in the southbound lanes near mile marker 129. She was taken to a nearby hospital, where she was later pronounced dead. Southbound lanes were shut down for roughly three hours as emergency crews worked the scene and traffic was rerouted, as per WKOW.
According to WKOW, the Dane County Medical Examiner's Office identified the victim as Victoria J. Biehl, 32, of DeForest. A preliminary forensic examination found that she died from injuries sustained in the crash, the medical examiner told the station. The Wisconsin State Patrol told the station the collision involved a semitruck and a passenger vehicle and that the agency is investigating.
Traffic safety context
Crashes involving passenger vehicles and commercial trucks can quickly turn fatal on high-speed corridors like I-90. The Wisconsin Department of Transportation reports the state recorded 127,551 crashes and 576 people killed in 2024, underscoring how fast a routine highway trip can become deadly. Impaired or speed-related driving were common factors in many fatal collisions. The state report is used by safety officials to prioritize enforcement efforts and roadway improvements.
Investigation and road impacts
The Wisconsin State Patrol led the response and closed southbound I-90 near mile marker 129 while troopers documented the scene and cleared the wreckage, according to WKOW. The lanes reopened after about three hours. Officials had not released additional details about the semitruck driver or any enforcement actions at the time of the report.
Investigators have asked anyone who saw the crash or who has video of the incident to contact the Wisconsin State Patrol as the investigation continues. This story will be updated if the State Patrol or the Dane County Medical Examiner's Office releases additional information.
