(WKBN) – Roads and bridges across the Valley were icy in spots, leading to crashes and traffic delays across the Valley on Thursday morning.

At least four vehicles were involved in a crash on the Himrod Avenue Expressway just before 8 a.m.

An ambulance was called to the scene, but the extent of any injuries is unknown.

The road was shut down until crews could tow several of the cars and clear the scene.

Just after 7 a.m., several Valley drivers also found themselves stuck in a traffic back-up on Interstate 80 in Liberty near the Belmont exit.

There was an accident with a fuel spill, though no injuries were reported.

The Ohio Department of Transportation did close Interstate 80 around 7:30 a.m., but it was reopened by 8 a.m.

A Youngstown City Schools bus was also involved in a crash with a vehicle at Market and Breaden streets in Youngstown. The driver of the car reported minor injuries, but no other injuries were reported.

Elsewhere, traffic was at a standstill on Interstate 680, just past Meridian Road heading toward Interstate 80 on Thursday morning. We had reports of at least three crashes in this area.

Our crews in the field said the bridges and overpasses were the slickest.
