FHWA Home / Safety / Roadway Departure / Longitudinal Barriers – NCHRP 350

Longitudinal Barriers – NCHRP 350

This listing contains barriers such as guardrail, median barrier, bridge railings and transitions that have been issued an Eligibility Letter by FHWA using NCHRP 350 testing criteria. 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."

These letters are archived and are posted for "historical and research purposes only" per the sunset dates in the AASHTO/FHWA Joint Implementation Agreement and exceptions to these dates as posted on the AASHTO Committee on Design website.

Note: Letters written for two or more configurations will be watermarked as archived, but they may have different sunset dates.
