Pittsburgh EMS, Fire and Police responded to Serpentine Drive near Bartlett Street in Schenley Park around 10:45 a.m. for a report of a large truck on its side with the driver still inside.

Responding Medics, Firefighters and Police Officers found a tri-axle truck that was fully loaded with asphalt on its side and on a hillside. The truck was part of a private contractor crew that is repaving Serpentine Drive.

The driver, who was still in the cab, was conscious, alert and communicating with rescuers.

Tow truck operators from McGann & Chester secured the truck to prevent it from slipping down the hillside. Medics from the Rescue Truck then scaled the hillside and extricated the driver, who said he had back and shoulder pain. The driver was transported to UPMC Presbyterian in stable condition.

Crews remained on scene to remove the truck. Park Rangers closed a trail below the hillside to prevent hikers from entering the area.

Police are investigating the cause of the crash.
