An existing bridge rail on a highway with a posted speed of 30 miles per hour or less may remain in place if it is not located on a bridge over a National Highway System (NHS) highway.

The barrier selection process includes consideration for speed, hazard offset and special design considerations for aesthetics and severe conditions. These considerations lead to a list of technically acceptable barriers for a specific site.

The evaluation should be based upon criteria similar to that shown in NCHRP Report"Multiple-Service-Level Highway Bridge Railing Selection Procedures." Guidance concerning width, rail and geometric criteria tradeoffs, and the effects on safety are contained in NCHRP's research Digest 98 and Report both entitled, "Safety at Narrow.
