The guardrail installation shall conform with Section 505 of the Virgina
Department of Transportation Road and Bridge Specifications, 2002.
Rail posts may be vertical or perpendicular to adjacent roadway grade
and cross slope. Grout may be used under base plates if necessary.
Details on this sheet are to be used for both straight and skewed
bridges.
Rail shall extend across joints with no change in post spacing or
continuity.

Anchor bolts shall be " o/A307 (or A36 threaded rods with tack
welded nuts) with hex nuts and washers as shown. Threaded rods may
be 0.781 min. diameter with rolled threads. Nuts shall conform to A307
requirements and shall be tapped or chased after galvanizing. Bolts
and nuts shall have Class 2A and 2B fit tolerances.

Tubular rail member shall be extended and connected to at least the

posts shall be used to utilize 25 ft. standard sections. Approach
guardrail posts shall be spaced at 6’-3" adjacent to the tubular rail
since its flexibility is similar to the standard metal beam guardrail.
Do not install additional posts at 3’-1" centers. Fully anchored
guardrail must be attached at both ends of tubular rail.

Test have shown that altough this rail deflects horizontally two or
three feet, adequate vehicle containment and re-direction is achived.
The resulting more gradual deceleration thus produces a safer condition than afforded by other bridge railings.

RAILING (TEXAS T-6)
NOTES TO DESIGNER:
Railing (CS-GR) may be used in lieu of cast-in-place concrete parapet (F-Shape) (CS-P1, CS-P2
and CS-P3) when the overall bridge length does not exceed 20’-0”. This bridge guardrail has
been crash tested for TL-2 (TL = test level).
ADD THE FOLLOWING NOTES, DIMENSIONS, DETAILS, ETC. TO STANDARD:
