A Note about Evolving Standards and Barrier Standard Plans
WSDOT continues, in cooperation with FHWA, its implementation of the AASHTO Manual for the Assessment of Safety Hardware (or MASH). MASH is the new national standard for crash testing and design of new roadside barrier. With the MASH implementation schedule now complete, the Design Office has recently removed a number of standard plans that do not represent MASH compliant design, while new designs are in development and published over time. In the meantime, these plans can be viewed on this page and may be incorporated into projects upon review and on a case by case basis. Please contact Tim Moeckel for more information.
