MILWAUKEE — A jackknifed semi closed the three right lanes on I-41/US/45 northbound at Mayfair Road on Tuesday morning, March 5.
It happened around 9:30 a.m. — and only involved the semi.
The driver was treated at the scene after suffering minor injuries in the crash.
The cause was under investigation.
All lanes reopened around 12:30 p.m. — but the crash caused big backups.
