The Coordinated Federal Lands Highways Technology Improvement Program (CTIP) was developed with the purpose of serving the immediate needs of those who design and construct Federal Lands Highways. A wide assortment of guardrails, bridge rails, and transitions are being used on roads under the jurisdiction of the National Park Service and other Federal agencies. These guardrails, bridge rails, and transitions are intended to blend in with the roadside to preserve the visual integrity of the parks and parkways. However, many of them have never been crash tested. A testing program was developed to ensure that the safety hardware used in these areas is safe for the traveling public. This report describes the safety evaluations which were included in the second Federal Highway Administration (FHWA) testing program - Guardrail Testing Program II - Systems tested under this program include the Steel-Backed Wood Rail to Bridge Rail Transition, the Foothills Parkway Memorial Bridge Rail, the Steel-Backed Log Guardrail, the Natchez Trace Parkway Bridge Rail, and the George Washington Memorial Parkway Bridge Rail. |
