A tractor-trailer was left hanging over an I-90 bridge and its driver is hospitalized after a crash Wednesday night.

It happened on the 90 in West Seneca on the overpass above Mineral Springs Road. 

Officers on scene say the truck caught fire but they're not sure if that's what caused the crash or if it happened after.

The driver jumped out and four good Samaritans help bring him to safety. 

He was taken to the hospital to be treated for burns.
