A jackknifed semi-truck on Interstate 80 has traffic on the road backed up for some distance Saturday evening.

The truck jackknifed just before 9:30 p.m. in the Eastbound lane near the Route 711 overpass in Girard.

At one point traffic was completely stopped in the lane as the truck was across the entire road.

The right lane of the road is now open as the scene is cleared.

It is unclear if anyone was injured.
