The Hospital for Special Surgery is planning a a $235 million construction project in New York City, but opponents say traffic congestion, horn-honking, and vehicle emissions in their neighborhood are already intolerable. The opponents argue trucks loading supplies or removing trash at the 145-year-old hospital are unable to fit into loading berths, so they block the street and create gridlock. The Hospital for Special Surgery performs more than 20,000 operations a year, and executives from the facility say it is at already at capacity despite a growing need for its services.
