Low speed bridges carrying both vehicular and non-vehicular traffic require a combination railing on the outside edge of bridge, adjacent to all pedestrian walkways, if a separator railing is not provided between the roadway and the sidewalk. A separator railing is not required on low-speed bridges, but may be considered on a case-by-case basis. If a separator railing is not provided, a raised pedestrian walkway is required. Refer to Figure B-2 for this situation. If a separator railing is provided, it is recommend to not have a raised pedestrian walkway as this can add significant load to the bridge. Refer to Figure B-3 for separator railing placement.
