Guardrail - C & W Construction Specialties

Our W-Beam to Thrie Beam transition panels are used to securely connect the guardrail to bridge railing or other concrete barriers or walls. Along with the other types of guardrail we sell, the transition rail is carefully designed to help maximize highway safety and mitigate any potential vehicular crash damage.

The use of this item will be determined by the design team case-by-case, depending upon applicability of bridge railing ,project scope, and site constraints. This MINNESOTA DEPARTMENT OF TRANSPORTATION Jul 11, 2019 · Standard Plate 8356A W-Beam to Thrie-Beam Transition Guardrail Transmittal Letter No. (19-03) General:1. This is a new Standard Plate detailing symmetrical and asymmetricalbeam/thrie w--beam (plate beam) guardrail transitions. 2. This Symmetrical W-Beam/Thrie-Beam Transition detail replaces Standard Plan 614. 3. Midwest Guardrail System W-Beam-to-Thrie-Beam TransitionThe basic design of the stiffness transition included standard MGS, a very stiff Thrie beam bridge rail, a previously accepted Thrie beam AGT system, and the asymmetrical W-beam-to-Thrie-beam

The new treatment consists of a single 10-ga. thrie-beam rail mounted at a height of 787 mm (31 in.) and supported on weakened, round wood posts. The Triple T:Truck Thrie Beam Transitionthrie beam transitions to a 3.8 m (12 ft 6 in.) long section of stan­ dard W-beam guardrail. The standard W-beam guardrail terminates with a 11.4-m (37-ft 6-in.) breakaway cable terminal. The total installation is 26 m (85 ft) long. Photographs of the completed installation are given in Figure 2.

STEP 1:Starting at the last post in the straight run (point A), lay cloth tape along the path that the curved guardrail will follow. STEP 2:Mark-off two points along the curved cloth tape:One at 6-3, or 1905 mm (point B) and the second at 12-6 or 3,810 mm. (point C). W-Beam to Thrie-Beam to Type F Barrier Transition - TypicalW-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, typically requiring Test Level 4 crash Midwest Guardrail System W-Beam-to-Thrie-Beam 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 e
