One person was killed early Thursday after two semi trucks collided on northbound I-43 near Highway 164 in Big Bend, shutting down the interstate and tangling the morning rush, authorities said. The crash happened just after 6 a.m. on the busy stretch that connects southern Waukesha County to Milwaukee. A second driver was taken to a nearby hospital with injuries described by the sheriff's office as not life-threatening.
What officials say
According to WTMJ, the Waukesha County Sheriff's Department said the wreck involved two semi-tractor-trailers and appeared to be a rear-end collision near the WIS-164 interchange. Deputies confirmed one person died at the scene, while the other driver was transported for treatment. Northbound I-43 was closed from WIS-83 to WIS-164 to allow investigators and cleanup crews to work, and officials had not yet released the names of those involved.
Traffic and travel impacts
A Wisconsin Department of Transportation camera feed showed traffic at a standstill as emergency crews responded, TMJ4 reported. The closure began around 6 a.m., leaving drivers stuck along the northbound lanes and clogging nearby routes. With the highway blocked, officials urged motorists to steer clear of the area and use alternate routes around the Big Bend interchange. Local authorities warned that the investigation and cleanup could keep the northbound lanes closed for hours.
How this fits into a worrying pattern
The I-43 corridor has seen several serious crashes this year, including an April incident in which a motorist was killed after being struck by a semi, according to WISN. Transportation advocates and local officials often point to the heavy mix of freight and commuter traffic on I-43 as a persistent safety challenge, especially during peak drive times.
Investigators with the Waukesha County Sheriff's Department are continuing their probe, and no charges had been announced as of the most recent reports. This story will be updated as officials release additional details.
