Dear Mr. Reynolds :
In your letter of September 26, 2009, you requested the Federal Highway Administration (FHWA) acceptance of the Little Brother x-footprint temporary sign stand as a crashworthy 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, aluminum laminates (2 mm and 3 mm), and corrugated plastic (up to 16 mm) sign substrate materials. 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 Little Brother. Drawings of the Little Brother are enclosed for reference. You requested that we find the Little 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, David A. Nicol, P.E. |
