Important Notice: Transition to MASH Compliant Systems

In line with Austroads’ transition to MASH-compliant systems, please be aware that certain transitions may no longer be approved for new installations in your jurisdiction. We recommend consulting your local Ingal Civil representative for further guidance. For a fully compliant MASH TL3 guardrail transition, please refer to our Ingal® RBT system.

Understanding Bridge Barriers and Guardrails

The most common types of bridge barriers include rigid barriers, which are made of reinforced concrete walls or metal rails mounted on concrete parapets. If not properly treated, the exposed ends of these barriers can present a significant hazard to errant vehicles. Typically, an approach guardrail is employed to shield these exposed ends and minimize the risk of vehicle impacts.

Guardrails are generally more flexible than the rigid barriers they connect to. Therefore, a transition section is necessary whenever there is an increase in stiffness from a semi-rigid W-Beam or Thriebeam barrier to a more rigid bridge barrier.
