Heavy Truck/F411 Bridge Rail Crash Test

Texas Department of Transportation (TxDOT) and Florida Department of Transportation frequently receive requests to provide aesthetically pleasing traffic rails for use on select bridges and roadways. TxDOT, in response to providing context sensitive design alternatives, initiated a project to develop additional aesthetically pleasing rail alternatives. The Texas T411 is an example of an aesthetic rail that has been successful and has seen widespread implementation at both the state and national level. Under a prior TxDOT project, an F411 bridge rail was constructed and crash tested to TL-3(3). The TL-3 test is a 4405-lb pickup impacting the railing at 25 deg. and 62.2 mph. This test requires both containment and stability and nonoverturning. Since some breakage of the parapet is possible, potential for vehicle snagging is likely. Vehicle snagging can contribute to vehicle instabilities in the redirection sequence and potential rollover. The TxDOT F411 bridge rail contained and redirected the vehicle, which remained upright during and after the collision period. The bridge rail met the required specifications for NCHRP Report 350 test 3-11.
