Report Number(s): 617741

Description: The installation consisted of a 128 foot long fence system mounted on a 130 foot long single slope concrete bridge rail. The bridge rail as 36 inches tall, 7.5 inches wide on the top, and 13 inches wide at the bottom. The sloped face of the bridge rail was on the impact side. The fence system was atached to the non-impacting side of the brisge rail and extended 9 ft 5 inches above the top of the concrete bridge rail. The main portion of the fence mesh was chain link fabric mounted to fense posts that were spaced at 96 inches center to center. Near the top of the concrete bridge rail, the fence posts were offset toward the field side. At top of the fence posts, the post pipes were bent toward the impacting side and connected to adjacent fence posts by a series of longitudinal pipes that were splaced together. A welded wire mesh panel was attached to the bent fence posts to cover the gap between the top of the concrete bridge rail and the chain link fence.
