Authorities responded to a crash that briefly snarled traffic Thursday afternoon in the northbound lanes of Route 28 just before the Aspinwall exit.
No one was injured.
Initial reports indicated the incident was a multi-vehicle crash shortly before 3 p.m. A school bus was spotted pulled over at the scene.
An Allegheny County 911 shift commander said Thursday evening said it was a single-vehicle crash involving a truck. The bus was not involved in the crash, the shift commander said.
Crews cleared the wrecked truck and reopened both lanes within about 30 minutes.
