Each barrier had two 3-inch tall × 22 inch long openings at the bottom, and three vertical holes on each side to receive anchor pins. The barriers were secured to the working slab with one 1-inch diameter × 25-inch long anchor pin located on the traffic side, at each end of each barrier units. These pins anchored the barrier units completely through a 10-inch thick unreinforced concrete slab and into the subgrade below.
