An accident briefly stopped traffic on the inner-loop of the West Shore Bypass in Reading.
The crash happened just beyond the on-ramp from Lancaster Avenue at the tail end of Tuesday morning's rush hour.
At least two vehicles, including a tractor trailer, were involved in the accident.
An ambulance responded to the scene, but police have not yet provided any information about the extent of injuries.
Westbound traffic was nearly backed up to the Interstate 176 interchange in Cumru Township until crews were able to clear the wreckage.
