Route 495 is a 3.45 mi freeway in Hudson County, New Jersey, in the United States that connects the New Jersey Turnpike (Interstate 95, I-95) at exits 16E and 17 in Secaucus to New York State Route 495 (NY 495) inside the Lincoln Tunnel in Weehawken, providing access to Midtown Manhattan.
 The road is owned and operated by the New Jersey Turnpike Authority (NJTA) between the New Jersey Turnpike and Route 3, the New Jersey Department of Transportation (NJDOT) between Route 3 and Park Avenue near the Union City–Weehawken border, and by the Port Authority of New York and New Jersey (PANYNJ) east of Park Avenue, including the helix used to descend the New Jersey Palisades to reach the entrance of the Lincoln Tunnel.
 Route 495 is mostly a six-lane freeway with a reversible bus lane used during the morning rush hour.
 The bus lane, which runs the entire length of the freeway, continues into the Lincoln Tunnel's center tube.
The construction of New York City's first World Trade Center complex was conceived as an urban renewal project, spearheaded by David Rockefeller, to help revitalize Lower Manhattan.
 The project was developed by the Port Authority of New York and New Jersey, which hired architect Minoru Yamasaki who came up with the specific idea for twin towers.
 After extensive negotiations, the New Jersey and New York state governments, which oversee the Port Authority, agreed to support the World Trade Center project, which was built at the site of Radio Row in the Lower West Side of Manhattan, New York City.
 To make the agreement acceptable to New Jersey, the Port Authority agreed to take over the bankrupt Hudson & Manhattan Railroad, which brought commuters from New Jersey to the Lower Manhattan site and, upon the Port Authority's takeover of the railroad, was renamed PATH.
The Statue of Liberty National Monument is a United States national monument located in the U.S. states of New Jersey and New York comprising Liberty Island and Ellis Island.

 The PABT, opened in 1950 between 8th and 9th Avenues and 40th and 41st Streets, was built to consolidate the many different private terminals spread across Midtown Manhattan.
 A second wing extending to 42nd Street was added in 1979.
 It is one of three bus terminals operated by the PANYNJ, the others being the George Washington Bridge Bus Station in Upper Manhattan and the Journal Square Transportation Center in Jersey City.
The World Trade Center site, formerly known as "Ground Zero" after the September 11 attacks, is a 14.6-acre (5.9 ha) area in Lower Manhattan in New York City.

 The Port Authority owns the site's land (except for 7 World Trade Center).
