A tractor-trailer jackknifed on the Pennsylvania Turnpike in Chester County as snow fell Thursday afternoon.
The crash caused the westbound lanes of the turnpike to be shut down between the Valley Forge (Exit 326) and Downingtown (Exit 312) interchanges around 1:45 p.m. The roadway remained closed until just before 6 p.m.
The detour at I-76 westbound was also lifted at Exit 326 and the Turnpike is open to westbound traffic.
Pennsylvania State Police said one person suffered a head injury.
There were two other separate crashes between mile-markers 314 to 315 westbound.
Troopers detoured motorists around the closed stretch suggesting drivers take U.S. Route 202 south for 12 miles to U.S. Route 30 West for 2,5 miles to state Route 100 north for five miles to Downingtown.
