Abstract:
On May 17, 2010, the FHWA issued memorandum HSSD, titled Roadside Design: Steel Strong Post W-Beam Guardrail, which revised their policy on the acceptable height of strong post w-beam barriers. That memorandum reflected the results of recent research which revealed performance issues for 27 inch high heavy-post w-beam guide rail and recommended consideration of systems 31 inches high. To expedite compliance, NYSDOT implemented a two-phase process. The first phase instituted intermediate changes to the existing HPBO systems through EB 11-034, which increased the rail height to 29 inches, but utilized the existing 8 inch blockout. This issuance institutes Phase Two, adoption of the 31-inch Midwest Guardrail System (developed by the Midwest Roadside Safety Facility), including conversion of all transitions. The increased rail height results in extra deflection and requires the use of the wider 12” blockout.
