A crash involving three vehicles, including a semitrailer truck and a school bus, tied up traffic for about an hour Tuesday morning on Interstate 35W in Minneapolis.

No one was seriously injured in in the crash, which happened just after 10 a.m. on northbound 35W between Lake and 26th Streets, the State Patrol said.

A semitrailer truck made contact with a vehicle causing that driver to lose control. The car hit a school bus, then hit the concrete median and rolled over, said Lt. Eric Roeske.

The wreck caused a traffic back up to 42nd Street for a short time until the wreckage was cleared.
