Development and MASH TL-4 Evaluation of TxDOT Large-Scupper Median Barrier for Flood-Prone Areas

Report Number(s): 0-6976-R1

Description: The installation consisted of five 30-ft-long scupper barriers spaced at 2 inches apart at the joints, for a total length of 150 ft 8 inches. Each barrier was anchored in place by two fully submerged 72-inch-long × 18-inch-diameter concrete pillars, spaced at 30 inches from the edge of the barrier to the center of the pillar. The barriers were 42 inches tall above grade, had a width on the bottom of 24 inches, and then sloped on both the traffic and field side for a final width of 8 inches at the top. The barriers also had a 13-inch-high scupper at the bottom, starting and ending at 72 inches from each end for an effective scupper length of 18 ft.
