HIGHWAY ACCIDENT REPORT; AUTOMOBILE CRASH OFF THE SILLIMAN EVANS BRIDGE, I-24/65, NASHVILLE, TENNESSEE, JULY 27, 1973

This report describes and analyzes the crash of a passenger car through the barrier system on the edge of the Silliman Evans Bridge (I-24/65) in Nashville, Tenn., on July 27,1973. Of the nine occupants in the automobile, the driver and seven passengers died. The sole survivor, a 5-year-old child, was moderately injured in the automobile's 65-foot fall to the ground. There was no fire, nor were there any ejections from the car. The National Transportation Safety Board determines that the probable cause of this accident was the failure of the driver to maintain her vehicle in the pathway provided. The following are contributing factors which may have confused the driver: (a) increasing curvature of the ramp; (b) narrowing of the ramp from two lanes to one; (c) a misleading traffic-control sign; (d) misleading pavement markings; and (e) an inadequately delineated and unnecessary section of a concrete island which narrowed the pathway to less than the width of a normal traffic lane--all in the last 600 feet of the ramp. This report contains recommendations to the Federal Highway Administration and to the State of Tennessee, which are intended to prevent the recurrence of an accident of this type.
