A crash on the inbound Parkway North near Perrysville caused a major traffic snarl this morning.
The crash, which may have been caused by icy conditions, occurred shortly before 7 a.m. and involved several vehicles.
All lanes were blocked for nearly an hour. The crash was cleared and the mainline reopened shortly before 8 a.m., but the HOV lanes remained closed until icing eased. The HOV lanes reopened around 8:15 a.m. and PennDOT temporarily waived the two-person occupancy rule in an effort to clear the major traffic backlog.
There were no immediate reports of injuries.
