One full-scale vehicle crash test was performed on Missouri's Modified Bridge Anchor Section. Test MBAS-1 was conducted with a 1985 Mercury Grand Marquis weighing 4,501-lbs (test inertial) at an impact speed of 59.0 mph and impact angle of 26.7 degrees. The impact location was 8 ft upstream from the end of the concrete barrier curb section. The test was conducted and reported in accordance with the requirements specified in the Recommended Procedures for the Safety Performance Evaluation of Highway Appurtenances, National Cooperative Highway Research Program (NCHRP) Report No. 230. The safety performance of Missouri's Modified Bridge Anchor Section was determined to be unacceptable according to the NCHRP 230 criteria.
