			Dear Mr. Reynolds:
			In your letter of April 10, 2009, you requested the Federal Highway Administration (FHWA) acceptance of the Econo Brother x-footprint temporary sign stand as a crash worthy traffic control device for use in work zones on the National Highway System (NHS). You requested acceptance of the temporary sign stand for use with roll-up sign substrate material. Your request for acceptance is based on the performance of the generic low mounted sign stands accepted in FHWA letter WZ-240 and a similar x-footprint sign stand in WZ-24. Accompanying your letter were the FHWA Office of Safety Design forms that included drawings and a detailed description of the Econo Brother. Drawings of the Econo Brother are enclosed for reference. You requested that we find the Econo Brother acceptable for use as a Test Level 3 device on the NHS under the provisions of the National Cooperative Highway Research Program Report 350 "Recommended Procedures for the Safety Performance Evaluation of Highway Features".
			This letter acknowledges FHWA's acceptance of your request. The original completed forms have been modified by the addition of the FHWA acceptance letter number and the date of our review. The form will be posted on our Web site in the near future.
			Sincerely yours,
						Signature of David A. Nicol, P.E.
