Some tires appear to be behind a tie-up on Highway 6 that left a dump truck on its side.
A little before 2 p.m. Friday, authorities believe someone travelling north near University Drive lost a couple of tires it was carrying. One of the bounding tires caused the southbound dump truck to swerve and lose control.
It came to rest on its side in the median, which caused some traffic to be rerouted.
The dump truck's driver had only minor injuries and refused medical treatment.
