minimum width of walkway
This clear width minimum is the minimum width for passage and not a sidewalk width recommendation [PROW Guide, Sec. 3.2.1]. The clear width is the width of section of the walkway that is completely free of obstacles, vertical obstructions and protruding objects. The 36 inch width is the minimum width required to provide sufficient space for a person who uses mobility aids to travel within the restricted space [ADAAG, Sec. 4.3]. However, restricting the pedestrian zone to 36 inches prevents passing and does not allow for 2-way travel.
