Dear Mr. Pasakarnis:

This is in response to your July 23, 2009, correspondence requesting the Federal Highway Administration’s (FHWA) acceptance of your company’s sign stand, model number UF2000T, as a crashworthy traffic control device for use in work zones and elsewhere on the National Highway System (NHS). Accompanying your letter was the FHWA Office of Safety Design form revising the FHWA Acceptance letter WZ-141 (including reference to WZ-17, WZ-25, and WZ-50) to include updated detail drawings of the UF2000T portable sign stand. This modification to the base of the UF2000 involves the addition of a tube receptor in-place of the current u-bracket to be compatible with the sign mast of the QFV-48. This minor modification in design that combines the UF2000 base with the QFV-48 sign mast will be model UF2000T. This modification will not adversely affect the crashworthy performance of this device and it is acceptable for use on the NHS.

You requested that we find this device acceptable for use on the NHS under the provisions of National Cooperative Highway Research Program Report 350 “Recommended Procedures for the Safety Performance Evaluation of Highway Features.”

This letter is the acknowledgement of the FHWA’s acceptance of your request. The original completed form has been modified by the addition of the FHWA acceptance letter number and the date of our review. The form, of which a copy is enclosed for reference, will be posted on our Web site in the near future.

 

Sincerely yours,

* Signature of Michael S. Griffith */
