The project evaluated bridge railings. State bridge rail designs submitted to the Federal Highway Administration (FHWA) were rated and the best of each type were selected for crash test evaluation. When necessary, the designs were improved and retested. Most of the crash tests were conducted with 4500-lb (2025-kg) cars at 60 mph (95 km/h) and a 25-degree angle and 1800-lb (800-kg) cars at 60 mph (95 km/h) and a 20-degree angle. Performance standards proposed in 1986 are presented, along with bridge railing geometric design considerations to minimize vehicle snagging. Design drawings of the successfully tested bridge rails are included.
