A trail bridge is a structure along a trail that spans over a waterway, precipitous slope, or other unstable ground that cannot support trail construction. Typically, a trail bridge is longer than a single span puncheon or boardwalk. If the height from the deck of the bridge to the ground or watercourse channel below is 48 inches or more, railings are required for safety. In addition to horizontal railings, a mid-rail or diagonal mid-rail is also necessary for edge protection.
