Abstract:The predominate bridge rail and approach guardrail transition (AGT) systems used among the New England states include details for 2-bar, 3-bar and 4-bar designs which were developed and tested under previous crash test standards (i.e., AASHTO GSBR PL2 and NCHRP Report 350). These basic designs are currently being implemented among various participating states using slight variations in design details, such as spacing between tube rails and curb height. The objectives of this study were to (1) conduct a detailed review of each State’s Standards to identify differences in design details and to recommend dimensional and material specifications to ensure consistency among the States and (2) to evaluate the crash performance of the NETC bridge rail and transition designs using finite element analysis (FEA) to determine if these systems comply with current test standards of MASH.
