SCRANTON, Pa. (WOLF) — Traffic backed up for miles Thursday afternoon after a tractor-trailer struck overhead exit signs on Interstate 81 northbound in Scranton, forcing traffic into a single lane.

As of 2:20 p.m. Thursday, October 8, I-81 northbound was down to one lane at the Biden/Central Scranton Expressway in Scranton, creating a 7-mile backup in Lackawanna County.

PennDOT said the lane restriction begins at the Biden Expressway in Scranton.

The estimated time of reopening is later this evening, and drivers are encouraged to take another route to their destination.
