A ventilation building was deemed to be architecturally unacceptable, hence the inclusion of several grates. On the other hand, gratings at Queensbridge Park were declared to be unfeasible due to the park's small usable area. Therefore, a ventilation building stands in Queensbridge Park, measuring . Additional ventilation shafts are located at Second Avenue and 63rd Street in Manhattan, and on the western shore of Roosevelt Island. When the 63rd Street Connector was constructed in the 1990s, additional ventilation structures were built at 29th and 39th Streets in Queens. The 63rd Street Tunnel and the 63rd Street Tunnel Connector received the Construction Achievement Project of the Year Award from the Metropolitan Section of the American Society of Civil Engineers in 1973 and 2000, respectively. The 63rd Street Tunnel Connector was also selected as the Transit Project of the Year in 1999 by "New York Construction News".
