A fuel truck crash on the Schuylkill Expressway brought traffic to a halt Friday morning, forcing cars to divert off the roadway.

The crash on the westbound lanes of Interstate 76 near Montgomery Drive caused the truck to flip to its side and spill fuel onto the road. Traffic on westbound lanes was completely halted, and eastbound lanes slowed to a crawl.

The westbound lanes were closed for more than two hours. One lane started to flow by the scene around 11:15 a.m. Police diverted westbound traffic off the Montgomery Drive exit.

Cars on the I-76 west on-ramp could be seen turning around and driving in the opposite direction to get out of the mess as police, firefighters and hazardous material crews worked to clean up the spill and right the overturned truck.

This is a developing story. Check back for updates.
