MARKHAM, Ill. (CBS) — Northbound Interstate 57 was turned into a virtual parking lot Thursday morning, as crews attended to a four-car pileup in a construction zone near the Tri-State Tollway.

As CBS 2’s Kris Habermehl reports, the four vehicles all rear-ended each other in a work zone on I-57 just south of the Tri-State sometime around 6 a.m.

Several ambulances from multiple southern suburbs responded to the scene, but the number and extent of injuries stemming from the crash was not immediately learned.

The left lane on northbound I-57 was blocked for cleanup from the crash, resulting in what Habermehl calls a “disaster.”

Slow travel times are expected between Interstate 80 and the Tri-State.
