ABSTRACT:

            The purpose of this research was to investigate the crashworthiness of a thrie-beam retrofit bridge rail with respect to MASH Test Level 3 (TL-3) performance criteria. This new bridge rail can be anchored to a concrete curb without removing the existing obsolete or historical bridge rail that is already in place. The research team designed and tested this new retrofit bridge rail for this project. The research team evaluated the structural capacity and the occupant risk factors of this new thrie-beam retrofit bridge rail design with respect to MASH TL‑3 criteria through full-scale crash testing.
