Construction of Ancillary 1 and Entrance 1 (northwest and northeast corners of 69th Street and Second Avenue respectively) will commence this month. The number of traffic lanes on Second Avenue must be reduced from four to three between 69th and 70th Streets to support these construction activities. Pedestrian walkways will be re-routed as necessary to support construction activities. Restaurant and stores will continue to have access to their entrances. This roadway traffic configuration will remain in effect until these structures have been built. Please see the new work zone configuration in the diagram below.

During this time there will be “NO STOPPING ANYTIME” along the western curb lane of Second Avenue from 69th Street to 71st Street. New signage will be posted to ensure motorists are aware of the new restriction and to maintain the curb lane. Drivers in violation of the new regulation will be ticketed.
