A semi-trailer truck jackknifed on the Tri-State Tollway, snarling northbound traffic during Monday’s morning commute.
The semi jackknifed across the Tristate Tollway just north of Grand Avenue about 6:45 a.m., according to Illinois State Police Master Sergeant Carlita Joe.
All lanes are blocked, Joe said. No injuries have been reported.
Joe said the semi is carrying plastic beads, which have spilled onto the Tri-State. State troopers and the Chicago Fire Department are on the scene.
