This listing contains information about work zone that have been issued an Eligibility Letter by FHWA based on AASHTO MASH 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." 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.
More information and resources are available at the Work Zone Clearinghouse and on the AASHTO Committee on Design website.

Evaluation of Work Zone Barricades and Temporary Sign Supports, Mak, Bligh, and Menges Report No. 5388-1 Sponsored by the Texas DOT.
Evaluation of Work Zone Barricades, Mak, Bligh, and Menges Report No. TX-97/3910-S Sponsored by the Texas DOT.
The tested portable sign stands were supplied by Traffix Devices Inc. and MDI-Windmaster. Roll-up sign sheeting was supplied by Reflexite. Plastic barricade panels were also supplied by Traffix. The acceptable portable sign stands all featured horizontal cross braces of lightweight fiberglass or plastic elements. Recent testing of some portable sign stands at 90 degrees shows that horizontal cross braces of tubular metal penetrate the windshield and are not considered crashworthy without additional testing. Portable sign stands with horizontal metal tubes (or other inflexible elements) supporting flexible signs may not be used on the NHS in a position where they could be struck at right angles.
Horizontal and upright components of the hollow core recycled plastic barricades were supplied by Recycled Plastic Products, Inc.
