Dear Mr. O’Neal:

This is in response to your September 17 e-mail correspondence requesting the Federal Highway Administration’s (FHWA) acceptance of your company’s ShowMeStand™ ground-mounted portable sign stand 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 and an engineering comparison with the Missouri Ground Mounted Temporary Sign Stand, covered in FHWA acceptance letter WZ-219. 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.” The Missouri stand was modified as follows:

The support tube (30" length galvanized “Telespar” 1-1/4" square perforated steel tube) will be replaced with galvanized or plain (painted) non-perforated 30 length of 1-1/4 square (11 gauge or 12 gauge) steel tube.

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 */
