Transportation

Roadways

The New Jersey Turnpike is one of the most prominent and heavily trafficked roadways in the United States. This toll road, which overlaps with Interstate 95 for much of its length, carries traffic between Delaware and New York, and up and down the East Coast in general. Commonly referred to as simply "the Turnpike", it is known for its numerous rest areas named after prominent New Jerseyans.

The Garden State Parkway, or simply "the Parkway", carries relatively more in-state traffic than interstate traffic and runs from New Jersey's northern border to its southernmost tip at Cape May. It is the main route that connects the New York metropolitan area to the Jersey Shore. With a total of fifteen travel and six shoulder lanes, the Driscoll Bridge on the Parkway, spanning the Raritan River in Middlesex County, is the widest motor vehicle bridge in the world by number of lanes as well as one of the busiest.

New Jersey is connected to New York City via various key bridges and tunnels. The double-decked George Washington Bridge carries the heaviest load of motor vehicle traffic of any bridge in the world, at 102 million vehicles per year, across fourteen lanes. It connects Fort Lee, New Jersey to the Washington Heights neighborhood of Upper Manhattan, and carries Interstate 95 and U.S. Route 1/9 across the Hudson River. The Lincoln Tunnel connects to Midtown Manhattan carrying New Jersey Route 495, and the Holland Tunnel connects to Lower Manhattan carrying Interstate 78. New Jersey is also connected to Staten Island by three bridges—from north to south, the Bayonne Bridge, the Goethals Bridge, and the Outerbridge Crossing.

New Jersey has interstate compacts with all three of its neighboring states. The Port Authority of New York and New Jersey, the Delaware River Port Authority (with Pennsylvania), the Delaware River Joint Toll Bridge Commission (with Pennsylvania), and the Delaware River and Bay Authority (with Delaware) operate most of the major transportation routes in and out of the state. Bridge tolls are collected only from traffic exiting the state, with the exception of the private Dingman's Ferry Bridge over the Delaware River, which charges a toll in both directions.

It is unlawful for a customer to serve themselves gasoline in New Jersey. It became the last remaining U.S. state where all gas stations are required to sell full-service gasoline to customers at all times in 2016, after Oregon's introduction of restricted self-service gasoline availability took effect.

Airports

Newark Liberty International Airport (EWR) is one of the busiest airports in the United States. Operated by the Port Authority of New York and New Jersey, it is one of the three main airports serving the New York metropolitan area. United Airlines is the airport's largest tenant, operating an entire terminal there, which it uses as one of its primary hubs. FedEx Express operates a large cargo terminal at EWR as well. The adjacent Newark Airport railroad station provides access to Amtrak and NJ Transit trains along the Northeast Corridor Line.

Two smaller commercial airports, Atlantic City International Airport and rapidly growing Trenton-Mercer Airport, also operate in other parts of the state. Teterboro Airport in Bergen County, and Millville Municipal Airport in Cumberland County, are general aviation airports popular with private and corporate aircraft due to their proximity to New York City and the Jersey Shore, respectively.

Rail and bus

NJ Transit operates extensive rail and bus service throughout the state. A state-run corporation, it began with the consolidation of several private bus companies in North Jersey in 1979. In the early 1980s, it acquired Conrail's commuter train operations that connected suburban towns to New York City. Today, NJ Transit has eleven commuter rail lines that run through different parts of the state. Most of the lines end at either Penn Station in New York City or Hoboken Terminal in Hoboken. One line provides service between Atlantic City and Philadelphia, Pennsylvania.

NJ Transit also operates three light rail systems in the state. The Hudson-Bergen Light Rail connects Bayonne to North Bergen, through Hoboken and Jersey City. The Newark Light Rail is partially underground, and connects downtown Newark with other parts of the city and its suburbs, Belleville and Bloomfield. The River Line connects Trenton and Camden.

The PATH is a rapid transit system consisting of four lines operated by the Port Authority of New York and New Jersey. It links Hoboken, Jersey City, Harrison and Newark with New York City. The PATCO Speedline is a rapid transit system that links Camden County to Philadelphia. Both the PATCO and the PATH are two of only five rapid transit systems in the United States to operate 24 hours a day.

Amtrak operates numerous long-distance passenger trains in New Jersey, both to and from neighboring states and around the country. In addition to the Newark Airport connection, other major Amtrak railway stations include Trenton Transit Center, Metropark, and the historic Newark Penn Station.

The Southeastern Pennsylvania Transportation Authority, or SEPTA, has two commuter rail lines that operate into New Jersey. The Trenton Line terminates at the Trenton Transit Center, and the West Trenton Line terminates at the West Trenton Rail Station in Ewing.

AirTrain Newark is a monorail connecting the Amtrak/NJ Transit station on the Northeast Corridor to the airport's terminals and parking lots.

Some private bus carriers still remain in New Jersey. Most of these carriers operate with state funding to offset losses and state owned buses are provided to these carriers, of which Coach USA companies make up the bulk. Other carriers include private charter and tour bus operators that take gamblers from other parts of New Jersey, New York City, Philadelphia, and Delaware to the casino resorts of Atlantic City.

Ferries

New York Waterway has ferry terminals at Belford, Jersey City, Hoboken, Weehawken, and Edgewater, with service to different parts of Manhattan. Liberty Water Taxi in Jersey City has ferries from Paulus Hook and Liberty State Park to Battery Park City in Manhattan. Statue Cruises offers service from Liberty State Park to the Statue of Liberty National Monument, including Ellis Island. SeaStreak offers services from the Raritan Bayshore to Manhattan, Martha's Vineyard, and Nantucket.

The Delaware River and Bay Authority operates the Cape May–Lewes Ferry on Delaware Bay, carrying both passengers and vehicles between New Jersey and Delaware. The agency also operates the Forts Ferry Crossing for passengers across the Delaware River. The Delaware River Port Authority operates the RiverLink Ferry between the Camden waterfront and Penn's Landing in Philadelphia.
