Curb extensions narrow the street by widening the sidewalk or the landscaped parking strip.
These devices are employed to make pedestrian crossings easier and to narrow the roadway. Curb extensions effectively improve pedestrian safety by reducing the street crossing distance and improving sight distance. They may also slightly influence driver behavior by changing the appearance of the street. They can be installed either at intersections or midblock. Curb extensions may occupy street area otherwise available for curbside parking.
