Dear Mr: Lund:

Thank you for your letter of August 29, 2006, requesting the Federal Highway Administration (FHWA) acceptance of your company's: A-Frame Type I and Type II barricades with vinyl I-Beam rails as crashworthy for use in work zones on the National Highway System (NHS). Accompanying your letter were drawings depicting the specified products. You requested that we find these devices: acceptable for use on the NHS under the provisions of the National Cooperative Highway Research Program Report3S0 "Recommended Procedures: for the Safety Performance Evaluation of Highway Features." In response to our request you sent additional information on November 13. 2006.

In support of your request, you referenced our October 2004 acceptance letter issued to a customer c of Cortina's proprietary PlastX A-Frame barricade (acceptance letter WZ-180), The A-Frame barricade tested and accepted is identical to Cortina's. The barricade was tested and accepted with a light-weight warning light (3.3Ibs) securely attached with a bolt. Cortina's I-Beam vinyl rails may be considered equivalent to previously accepted thermoplastic I-Beam rails. Therefore, your company's parade style barricades using Cortina's vinyl I-Beam rails or other previously accepted rails up to 12 feet long with a top rail height measuring no taller than 44 inches, and with a light-weight warning tight securely attached (not to exceed 3.3 lbs) are acceptable for use on the NHS, when proposed by a State.

Please note the following standard provisions that apply to the FHWA letters of acceptance:

Sincerely yours,
