A total of seven vehicle crash tests were performed, three involving a Type 115 bridge rail and four involving a thrie beam bridge rail. Additional static testing was done on five steel bridge rail posts with different types of post stiffeners. The Type 115 bridge rail consisted of two tube steel rails (4x4x0.25 in.) supported off the edge of deck by steel wide flange posts at 8 ft 0 in. spacing. The thrie beam bridge rail consisted of 10 ga. thrie beam panels blocked out and supported on the edge of deck by steel wide flange posts at 6 ft 3 in. spacing. The typical heights for the Type 115 and the thrie beam bridge rails were 30 and 32 in., respectively. There were two impact tests on the Type 115 bridge rail, one on the Type 115 bridge rail transition, two on the thrie beam bridge rail, and two on the thrie beam bridge rail transition.

The objective of the research project was to collect crash test data relating to bridge rails and median barriers, to collect information about common attachments to traffic barriers, and to evaluate this information for the purpose of developing guidelines for the design and placement of traffic barrier attachments. A comprehensive review of full-scale crash testing of bridge rails and median barriers was conducted in order to establish Zones of Intrusion (ZOIs) for traffic barriers. The primary goal of this review was to identify the extent that a pickup or single-unit truck intrudes over the top of a traffic barrier during a vehicular impact.
