Neckdown / Curb Extension / Bulb-Out A widened section of sidewalk that extends into the roadway at an intersection or mid-block crossing, shortening the pedestrian crossing distance.
These are generally city-designed streetscape features rather than something an individual property owner builds, installed as part of broader traffic-calming or pedestrian-safety projects led by DOT. Once in place, a neckdown's sidewalk surface follows the same maintenance rules as any other sidewalk, meaning the adjacent property owner may still bear repair responsibility for cracking or settling within it, depending on its exact location relative to their frontage. Confirming responsibility for a neckdown's upkeep is worth doing before assuming it's automatically a city repair.
