New York City is the top international air passenger gateway to the United States. The area is served by three major airports, John F. Kennedy International, Newark Liberty International and LaGuardia, with plans for a fourth airport, Stewart International Airport near Newburgh, New York, to be taken over and enlarged by the Port Authority of New York and New Jersey (which administers the other three airports), as a "reliever" airport to help cope with increasing passenger volume. 100 million travelers used the three airports in 2005 and the city's airspace is the busiest in the nation. Outbound international travel from JFK and Newark accounted for about a quarter of all U.S. travelers who went overseas in 2004. JFK Airport is the largest hub for JetBlue. It is the fourth largest hub for American Airlines and is the sixth largest hub for Delta Air Lines. Newark Airport will be the third largest hub for United Airlines once they complete their merger with Continental Airlines. This will make United Airlines the largest airline in the New York market.
New York's high rate of public transit use, 120,000 daily cyclists and many pedestrian commuters makes it the most energy-efficient major city in the United States. Walk and bicycle modes of travel account for 21% of all modes for trips in the city; nationally the rate for metro regions is about 8%.
To complement New York's vast mass transit network, the city also has an extensive web of expressways and parkways, that link New York City to northern New Jersey, Westchester County, Long Island, and southwest Connecticut through various bridges and tunnels. Because these highways serve millions of suburban residents who commute into New York, it is quite common for motorists to be stranded for hours in traffic jams that are a daily occurrence, particularly during rush hour. The George Washington Bridge is the world's busiest bridge in terms of vehicle traffic.
Despite New York's reliance on public transit, roads are a defining feature of the city. Manhattan's street grid plan greatly influenced the city's physical development. Several of the city's streets and avenues, like Broadway, Wall Street and Madison Avenue are also used as metonyms for national industries located there: the theater, finance, and advertising organizations, respectively.
