Duration: 9:15 The thrie beam guardrail has been modified to improve performance in large-vehicle impacts by increasing the depth and energy-absorbing capacity of the block-out. Crash tests show that this design can safely contain and redirect a wider range of vehicles than other W-beam designs. Terminals and transitions are shown. Costs of installation and repair are discussed, and the design is recommended for sites with heavy traffic. Download The Modified Thrie Beam Guardrail from The Internet Archive
