18 Wheeler Leaves the Interstate, Rolls Over CHATTANOOGA, TENN – Sometime around 3:00 AM, Friday, September 21, 2007, the Chattanooga Fire Department responded to the junction of Interstate 75 and Interstate 24 on a reported tractor trailer overturned with entrapment. Chattanooga Fire Department Quint 8 and Quiet arrived at almost the same time.  Captain Ken Moses with Quint 8 cancelled the Squad Trucks with regard to extrication and his personnel along with those from Quint 13 were able to free the driver.   The tractor trailer combination was southbound on Interstate 75 just past the junction where it splits and becomes I-24 west as I-75 continues south into Georgia.  The driver continued west on I-24 for a few hundred feet and then veered off of the roadway to the left, down an embankment, through a small thicket of trees and back up an incline before the rig rolled over on its right side.  There were no other vehicles involved in the crash. Workers from Yates Wrecker Service were on hand through the night working to get the 18 wheeler upright and then remove it.  They were finally able to do so shortly before 9:00 AM.  This area is extremely heavily traveled all of the time but especially during rush hour.  Even though the wreckage was well off the roadway, traffic was slowed to a crawl during the morning hours as those passing by slowed and even stopped in some cases to look at the accident scene.  The tractor trailer is registered to Grand Traverse Trucking in Traverse City, Michigan.  It is unknown what it was hauling at the time of the accident.  The investigation into the cause of the accident is being handled by the Chattanooga Police Department.
