Transitions to rigid barrier, also known as bridge approaches, are a specially designed interface providing a smooth, snag-free transition between different types of safety barrier systems. 

The transitions are designed for attachment directly to RamShield® Guardrail and feature thrie-beam guardrail supported by posts at reduced spacings which gradually increase the guardrail barrier stiffness prior to connecting to the rigid barrier.

The use of a transition reduces the potential for vehicle pocketing at the connection between the guardrail system and rigid barrier.

Transitions to Rigid Barrier FAQs

When are Transitions required?

A transition is required whenever a guardrail barrier is connected to a rigid barrier. This includes concrete barrier, bridge barrier or a bridge abutment.

Is thrie-beam guardrail required for the assembly of a Transition to Rigid Barrier?

Yes. The additional corrugation of thrie-beam when compared to w-beam increases the stiffness of the guardrail system which is an important design feature of the Guardrail Transition.

How does the transition connect to the concrete barrier or bridge abutment?

A thrie-beam terminal connector is used to fasten the last thrie-beam panel to the rigid structure.

What is the post spacing of the Transition to Rigid Barrier?

The post spacing of the guardrail transition is system dependant. Please refer to assembly drawings provided by Safe Direction.
