• Abstract:
  There are over 400 buried concrete barrier ends on Washington state routes. While buried concretebarrier ends are no longer included in standard plans, it is not well understood how vehicles are interacting with these structures. An inventory of buried concrete barrier ends was matched with crash data sourced from the WSDOT Engineering Crash Datamart and the Crash Location & Analysis System (CLAS) database for the years 2011 through 2020 to determine the distribution of crashes in location and severity. During this ten-year period, 36 crashes with these ends were reported and they included only one fatal crash and no serious injury crashes. Most crashes occurred in an urban environment with almost an even split between mainline and exit ramps.
