It happened around 3:30 a.m. Tuesday on the 30th Street westbound ramp to the westbound Schuylkill Expressway.
The tractor-trailer got stuck on a concrete barrier. It appeared the driver was making a left on the ramp, which is the wrong way.
Police were on the scene redirecting traffic. Crews removed the truck from the barrier around 7:30 a.m.
No injuries have been reported.
