Drop curb A drop curb is a section of curb that is lowered to create a smoother transition between the sidewalk and the roadway. It is commonly installed where vehicles or pedestrians need easier access.
In NYC, the term may refer to a lowered curb serving a driveway or an accessible pedestrian crossing, depending on the location. The design must match approved grades so water continues to drain properly while providing safe access. Drop curbs are often constructed as part of driveway, curb cut, or accessibility improvements.
