It happened early Sunday morning in the westbound lanes at the Conshohocken Curve.
Police say the driver lost control, hit a pile of snow and flipped over the guardrail.
The driver was then able to get out of the car and climb back up to the expressway where he was picked up and taken to the hospital for minor injuries.
Police say if the car didn't get tangled up in some trees, the accident could have been much worse.
