Test Level 2 Guardrail-to-Bridge Rail Transition Compatible with 31-in. Guardrail
RP Bligh, DR Arrington, R Meza - Transportation research …, 2013 - journals.sagepub.com
Many state departments of transportation are in the process of updating their guardrail
standards to comply with the AASHTO Manual for Assessing Safety Hardware (MASH) and
guidance issued by FHWA on guardrail height. A key feature of the new systems is an
increase in rail mounting height from 27 in. to 31 in. A common application of guardrails is
shielding motorists from hazards at bridge approaches, including the end of the bridge rail.
When a flexible-approach guardrail is attached to a rigid bridge rail, a transition section is …

The TxDOT Design Division is in the process of developing new guardrail standards that
comply with the AASHTO Manual for Assessing Safety Hardware (MASH). The new
guardrail system will provide increased capacity and improved impact performance relative
to the current design. A key feature of the new system is an increased in rail mounting height
from 27 inches to 31 inches. TxDOT's current TL-2 metal beam transition is 27 inches tall
and is not compatible with the new 31 inch guardrail system. While the high-speed, nested …
