The collision happened around 9:30 a.m. Tuesday, Sept. 3, near Cloverleaf Road, the supervisor said. Westbound lanes remained closed for hours until reopening in the afternoon.
Two people were taken to an area hospital, and two people were treated at the scene, according to the supervisor.
Traffic was backed up for miles following the crash.
Officials also cleaned up a diesel fuel spill from the tractor-trailer.
