Work Zone Devices

This listing contains information about work zone devices that have been evaluated in accordance with the AASHTO MASH or NCHRP Report 350. 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.

When NCHRP Report 350 was implemented, FHWA created four categories of work zone devices. AASHTO is considering if these categories are still appropriate for MASH.

More information and resources are available at the Work Zone Clearinghouse.

The listing below is primarily of the Category II and IV devices. The Category I are self certified and the Category III are typically barrier or crash cushions that are included in other lists.

This table is an updated version of the one included in the FHWA Memorandum
"Crash Tested Work Zone Traffic Control Devices," Dated August 28, 1998

  • 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 (*).

Revised, Wednesday, October 18, 2017



**The FHWA Federal-aid Eligibility letters for this device will be rescinded on May 26, 2018 if the conditions of Section 1 of FHWA's May 26, 2017 open letter https://safety.fhwa.dot.gov/roadway_dept/countermeasures/reduce_crash_severity/ openletter052617.cfm) are not met. After May 26, 2018, FHWA would consider assurance from the State DOT or local agency that the device is crashworthy (most often evidenced by including the device in State DOT or local agency standards and specifications) in making a determination of eligibility for reimbursement from the Federal aid program.

Notes:

  1. Evaluation of Work Zone Barricades and Temporary Sign Supports, Mak, Bligh, and Menges Report No. 5388-1 Sponsored by the Texas DOT.

  2. Evaluation of Work Zone Barricades, Mak, Bligh, and Menges Report No. TX-97/3910-S Sponsored by the Texas DOT.

  3. 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.

  4. Horizontal and upright components of the hollow core recycled plastic barricades were supplied by Recycled Plastic Products, Inc.
