A tractor-trailer overturning on the roundabout near the I-70 westbound exit in New Stanton snarled traffic on the Pennsylvania Turnpike on Tuesday evening.
The tractor-trailer overturned at 5:33 p.m. Tuesday at the roundabout, according to a Westmoreland County 911 dispatcher.
There were no injuries, the dispatcher said.
PennDOT cameras showed a traffic backup on the Turnpike at the New Stanton interchange. The dispatcher said that was due to the crash and construction on the Turnpike.
A reopening time was unknown. The ramp was still closed as of 8:18 p.m.
