9th Street–Congress Street station is notable for having a pair of elevators that runs along the face of the Palisades cliffs between the platforms at their base and Paterson Plank Road at their crest. Use of the elevators is free. Before its construction, travel between Jersey City Heights and Hoboken was along Paterson Plank Road, Mountain Road, 14th Street Viaduct or paths along the cliffs now made inaccessible by fencing along the right of way.[3]
