FHWA Eligibility Letters for Category II Work Zone Devices

View list of all FHWA Eligibility Letters covering Work Zone Devices starting with those most recently posted.

The new search feature for crashworthy work zone traffic control devices allows you to zero in more quickly on the eligibility letter or letters that include the hardware you are interested in. Every FHWA Eligibility Letter has been reviewed for the following information, and the appropriate keywords have been associated with each Eligibility Letter:

To sort these letters to find those associated with the keywords you are interested in you may choose the Keyword Table method, or the Dropdown Menu method.

If you choose the Keyword Table method you will see five tables showing all the keywords in the categories listed above. Click on any keyword of interest. The program will then sort out those letters associated with your keyword of interest, and present you with a revised set of tables.

For example, if you are interested in x-footprint sign stands that have been crash tested with plywood signs, begin by clicking on "X-Footprint Sign" in the "Type of Device" table. You will then see that the keywords now available in the tables has been reduced. Only those letters that include x footprint signs are sorted. Click on "Plywood" in the "Sign Substrate or Barricade Rail" table and you will see the short list of Eligibility Letters that cover X-Footprint Signs and Plywood Sign Substrates. Please note that this does not necessarily mean that all those letters cover plywood signs mounted on x-footprint sign stands. The letters may deal with tripod stands that support plywood signs and x-footprint stands supporting roll-up signs. You will have to review the content of the letter to ensure that the hardware meets your needs.

If you choose the Dropdown Menu method, you may select keywords from any or all of the menus, then click "Search by Keyword" to get the list of letters that meet all of your criteria. If you get "No records meet your search criteria" as a response, change one or more of the Dropdown Menus to "All" and try again.
