FHWA Home / Safety / Roadway Departure / Longitudinal Barriers

Longitudinal Barriers

This listing contains barriers such as guardrail, median barrier, bridge railings and transitions, that have been issued an Eligibility Letter by FHWA. The FHWA's Federal-aid eligibility letters are provided as a service to the States and are not a requirement for roadside safety hardware to be eligible for Federal-aid reimbursement. As stated in our eligibility letters, "eligibility for reimbursement under the Federal-aid highway program does not establish approval, certification or endorsement of the device for any particular purpose or use." It is the responsibility of the agency who owns the facility to determine whether or not to use a particular hardware device and how to use it for the particular situation. See AASHTO's Roadside Design Guide and AASHTO's Manual for Assessing Safety Hardware for guidance on selecting the appropriate Test Level (TL) based on traffic using the facility.

Note: May 30, 1997 – ACTION: Crash Testing of Bridge Railings still in effect until sunset dates in the AASHTO/FHWA Joint Implementation Agreement for MASH.

AASHTO Task Force 13 Guide for Barriers provides further information for specific barrier hardware systems, bridge railings and transitions.

Longitudinal Barriers and Miscellaneous Items

  • Select "MASH" for crashworthy systems per the AASHTO Manual for Assessing Safety Hardware
  • Select "350" for crashworthy systems per NCHRP Report 350
  • Select "All" for both "MASH" and "350".

Recently posted Eligibility Letters are marked with an asterisk (*).
