摘要：	The Type 732SW bridge rail is an updated version of the Type 26 bridge rail and was tested for compliance to the Manual for Assessing Safety Hardware (MASH 09) as a part of this research project. The 732SW is a taller, stronger version of the Type 26 with a sidewalk. It is comprised of a sidewalk, vertical concrete wall, and steel handrail for pedestrians. The barrier tested was about 24 m (79 ft) long and was constructed at the Caltrans Dynamic Test Facility in West Sacramento, California. Three crash tests were conducted under MASH 09: Test 3-11 (the 2270P pickup at TL-3), Test 3-10 (the 1100C small car at TL-3), and Test 2-10 (the 1100C small car at TL-2) because Test 3-10 resulted in a ridedown acceleration that was outside of the MASH 09 limits. The results of Tests 3-11 and 2-10 were within the limits of the MASH 09 guidelines. The Type 732SW bridge rail is recommended for approval on California highways requiring TL-2 bridge rails with pedestrian traffic. Since it is symmetric, the Type 732SW is also recommended in locations where a reverse hit is possible.
