Guardrail is typically more flexible than the bridge rails to which they are attached.A transition section is therefore required wherever there is a change in the deflection characteristics between the approach guardrail and bridge rail or between different barrier systems.Guardrail Systems Field Guide For Construction The SRT guardrail panels have two sets of three long slots with a slot guard bolted on the downstream side of the slots. These slots should be between posts 1 and 2,2 and 3,3 and 4,and 4 and 5.Toward Post 1 CDOT Guardrail Systems Field Guide for Construction Engineers and Inspectors Page 12of 57Guardrail Systems Field Guide For Construction The SRT guardrail panels have two sets of three long slots with a slot guard bolted on the downstream side of the slots.

Design - Plan Sheet Library - Beam Guardrail Transition

Tim Moeckel 360-704-6377 This Plan is intended to depict a Beam Guardrail Transition system used to transition from Beam Guardrail Type 31 to another structure.This System could be used where there is limited length available and a Standard Transition will not fit.Design - Plan Sheet Library - (Old) Type 1 Beam Guardrail A transition stiffens the more flexible barrier by decreasing the post spacing,increasing the post size,and using stiffer beam elements to reduce the possibility of pocketing.Note WSDOT introduced Type 31 guardrail in 2009 as the replacement for Type 1 guardrail.Chapter 4 Construction Details,Section 83 Railings and Guardrail must be anchored at both ends,in the same way a railing of rope would need to be anchored to function properly.Guardrail is normally anchored with a terminal system,an end anchor,such as a steel foundation tube or a buried post end anchor,or anchored to a structure using a transition detail.
