W-Beam to Thrie-Beam Transitions

For longitudinal barriers, it is common practice to use a standard W-beam guardrail along the required highway segments and to use a stiffened thrie-beam guardrail in a transition region near the end of a bridge. As a result of the differences in rail geometries, a W-beam-to-thrie-beam transition element is typically used to connect and provide continuity between the two rail sections. 
W-Beam to Thrie-Beam to structure transitions are typically used and specified in guardrail terminations to bridges, concrete abutments, concrete structures and crash cushions.
The transitions are also used to transition into Thrie-Beam installations for reasons such as reducing guardrail deflection and providing greater protection for heavier vehicles, 
W-Beam to Thrie-Beam Transitions consists of W-Beam, Thrie-Beam, C-Block, C-Posts, Thrie-Beam Terminal Connector (optional) and associated hardware fixings.
Details and requirements such as spacing's of posts, rail nesting, terminal connections and installation heights do vary across the different state road authorities.

Thrie-Beam Guardrail
Thrie-beam guardrail is a stronger version of the w-beam guardrail systems. The additional corrugation in the thrie-beam rail stiffens the system, making it less prone to damage during low- and moderate-speed vehicle impacts.
The higher mounting of the thriebeam rail, increases its ability to contain vehicles larger than standard passenger cars under some impact conditions.
Specifications
Manufactured in accordance with state road agency specifications
Hot dip galvanised components in accordance with AS/NZS 4680.
Features
The additional corrugation of the thrie-beam rail stiffens the system
when compared to w-beam systems.
The post and block design reduces wheel snagging and the
consequential effects of vehicle vaulting or rollover.
