Figure 17 is a set of two line drawings illustrating mid-block and corner combination curb ramps.
A sidewalk width of at least 6 feet is required. The sidewalk ramps down like a parallel curb ramp
at a 1:12 slope to a level landing 5 feet in length. From this landing, a short perpendicular curb
ramp, also at a 1:12 slope, connects to the street at the curb. Where two curb ramps are used at
an intersection, it is not necessary to ramp the sidewalk back up to the original curb height as it
goes around the corner; it can connect at the lower height to the second curb ramp.
