A semitrailer driver has been cited in a crash that closed the southbound lanes of I-43 north of the Mitchell Interchange for most of the day Monday.

According to a Milwaukee County Sheriff's Office news release:

Ali Z. Abubakar was driving the semi southbound on I-43 north of Layton Avenue about 11:15 a.m. when he struck a tow truck that had responded to an earlier crash.

The crash was captured on the dash-cam video of a sheriff's deputy who responded to the earlier accident.

The force of the crash caused the cab and the trailer to separate, flipping the semi on its side and blocking all three lanes of traffic.

The crash slammed the tow truck into a wall, trapping that driver in the cab. The driver had to be cut from the wreckage by firefighters. He was taken to a hospital with serious but non-life-threatening injuries.

Hazardous materials crews and highway maintenance workers also responded to clean up the freeway, according to emergency radio traffic from Broadcastify, a platform for streaming live audio of public safety, aircraft, rail and marine-related communications. The audio reflects about 30 minutes of radio transmissions edited for brevity and elimination of gaps and garbles.

Abubakar and his passenger were able to climb out of the semi cab and were taken to a hospital with cuts on their heads and arms.

Abubakar, who holds a valid commercial driver's license from Ohio, was hauling 6,000 pounds of light fixtures. He was issued citations for driving too fast for conditions and failure to keep a vehicle under control, both of which include fines of $224.

All lanes were reopened about 3:40 p.m.
