A concrete ramp is detailed with a 1:12 maximum slope and a maximum 2% cross-slope, bounded by an adjacent wall and a 4-inch high concrete curb. The assembly includes a detectable warning surface adjacent to the ramp termination. A 36-inch high pipe handrail is specified alongside the ramp. Dimensioning indicates a 48-inch minimum width with specific segment lengths of 3 feet 6 inches, 3 feet 8 inches, and 6 feet.
