The Ohio State Highway Patrol is investigating thirty accidents that occurred in less than a three-hour period during icy conditions on highways in the Valley.

Drivers found icy bridges on their morning commute Thursday. Troopers reported 17 crashes in Trumbull County and 13 in Mahoning County.  Those numbers don't include crashes being investigated by local police departments.

Troopers say there were some injuries reported, but not of them were serious.

An accident in the area of Route 11 and I-680 in Austintown backed up traffic into Youngstown. An Austintown Fire rescue vehicle on the way to that crash struck a barrier on the highway. Fire Cheif Andy Frost estimates damage to the truck at around $200.

The most extensive traffic backup was caused by a tractor-trailer accident on westbound Interstate 80 just east of the Salt Springs Road interchange. 

There were so many accidents, dispatchers in Trumbull County said they were running short of emergency crews to respond.  Trumbull 9-1-1 took 20 accident calls within a half hour.

An accident temporarily shut down the Route 5 Bypass at Route 422. The bypass was the scene of numerous crashes.

In Youngstown, two northbound lanes of I-680 were closed near Midlothian Boulevard after an accident.

Northbound traffic was backed up on Interstate 680 in Austintown near Route 11 road because of a crash.

Another crash was reported on Route 82 eastbound just east of Warner Road.

The red and orange designations on the map below show the areas where traffic was either stopped or slowed.
