PIQUA — A semi-tractor trailer crash left traffic backed up for miles on southbound Interstate 75 on Thursday.

The Ohio State Highway Patrol reports the crash occurred shortly after 3 p.m. on Thursday, Feb. 9, when the driver of a southbound truck lost control of his vehicle and struck a concrete bridge around the 80 mile marker.

The commercial truck was carrying large coils of steel, one of which broke loose and partially uncoiled.

The driver of the truck was not injured.

Southbound traffic on I-75 was re-routed across U.S. Route 36.

State troopers were able to re-open the highway around 8:15 p.m.
