Bridge rail surface treatments, such as form liners may be used on the field side of the rail. The rail standard must be modified to increase the clear cover by the depth of reveals or amplitude of the pattern.

Stone or brick grouted veneers may not be used on top of the rail, the traffic face, or field side over grade separations or interchanges.

Treatments, such as form liners, on the traffic face of the bridge rail must be approved by Bridge Division.

Treatments must not have a component that could become an intrusion threat or snag any part of the vehicle.
