Dear Mr. Goode:
This is in response to your November 22, 2010, correspondence requesting the Federal Highway Administration's (FHWA) acceptance of your company's SZ-BTS Portable Sign Stand as a crashworthy traffic control device for use in work zones and elsewhere on the National Highway System. Accompanying your letter was the FHWA Office of Safety Design form and drawings of the stand. 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 and includes the original completed form, the Test Data Summary Sheet, and drawings of the relevant sign stand.
Sincerely yours,
Signature of Mike S. Griffith
