A northbound lane of Interstate 79 in Robinson was closed for several hours Monday morning because of a tractor-trailer crash, according to PennDOT.
The crash occurred shortly after 3 a.m. 0.6 miles south of Exit 64, which is the Coraopolis/McKees Rocks exit.
No injuries were reported.
Both travel lanes were reopened shortly after 7 a.m. after emergency responders up righted the vehicle, which lost its rear axle when it flipped onto its side, according to state police.
