For all zoning lots abutting bridge structures supporting streets which cross the Gowanus Canal at Union Street, Carroll Street, and Third Street, and are subject to waterfront public access area requirements, such waterfront public access area shall be designed to provide pedestrian connection to the street adjacent to the terminus of the bridge structure.

The requirements of this Section may be waived where the Commissioner of the Department of Buildings determines, in consultation with the Department of Transportation, that such a pedestrian connection to the street would result in a hazard to pedestrian or traffic safety.
