Nearly a dozen crashes snarled traffic Tuesday morning on highways west and south of Pittsburgh.
Among the more major incidents, a multi-vehicle crash just before 7 a.m. on Interstate 79 southbound at the Carnegie exit closed all lanes for a time, according to PA511.
Backups from the closure spilled onto the Parkway West. As of 8 a.m., traffic was moving again but quite slowly.
Another multi-vehicle crash around 7:30 a.m. on I-79 southbound at Exit 54 (PA 50, Bridgeville) left all lanes closed. Crews worked to clear the vehicles and reopened the lanes just before 9 a.m.
PA511 shows at least three other crashes along I-79 were also impacting traffic.
Meanwhile, there were also overturned vehicles on both sides of the Parkway West near Pittsburgh International Airport.
The crashes slowed down traffic in both the westbound and eastbound lanes.
The eastbound crash happened between Pittsburgh International Airport and McClaren Road.
Several other incidents were reported along the Parkway West and on Route 30 near the Oakdale exit.
