Curb Ramps at Intersections

Curb ramps at marked crossings must be wholly contained within the crosswalk, excluding side flares. The Standards do not require crossings to be marked or address how they are to be marked, but public street crossings are addressed by the Manual on Uniform Traffic Control Devices (MUTCD) for Streets and Highways.

Curb ramps must be oriented so that the grade break is perpendicular to the curb ramp run to ensure a smooth transition to streets, including at corners with a wide radius. The curb ramp opening can be aligned with the curb line (left) or more directionally oriented to the crosswalk (right).

One figures shows curb ramps at corner with wide radius that are aligned with the curb line and another where the curb ramps or more directionally oriented to the crosswalk.
