New Jersey is situated between Philadelphia and New York City, two major metropolitan centers of the Boston-Washington megalopolis, making it a regional corridor for transportation.
The main thoroughfare for long distance travel is the New Jersey Turnpike, the nation's fifth-busiest toll road.
[5] New Jersey has a statewide mass transit system, centered on transportation to New York City and Philadelphia.
Intercity rail is operated by Amtrak along the Northeast Corridor between the major population centers of the Northeastern United States.
[7] The major roadways fall under the jurisdiction of the New Jersey Department of Transportation (NJDOT), which operates the state highway system.
According to the NJDOT, a jughandle is an "at-grade ramp" provided at or between intersections to permit motorists to make indirect left turns and/or U-turns.
"Type C" is the standard reverse jughandle; left-turning vehicles pass through the intersection and enter a ramp that loops roughly 270 degrees.
[12][13][14] A Right-in/right-out (RIRO) expressway (also called a Jersey freeway) is a partially limited-access divided highway without at-grade intersections.
To increase safety, RIRO expressways have a continuous median barrier and speed limits are lower than typical freeways.
The Interstate Highway System includes 431 miles (694 km) of New Jersey's expressways and carries 20 percent of all vehicle travel.
The system is composed of principal arterial roads, which may feature jughandle ramps, interchanges, and traffic circles at major junctions.
In addition, New Jersey toll roads are assigned internal numbers by NJDOT—the New Jersey Turnpike is 700 (south of the split with I-95), the Garden State Parkway is 444, the Palisades Interstate Parkway (not tolled, but maintained by the Palisades Interstate Park Commission) is 445, and the Atlantic City Expressway is 446.
Tolls are collected in one direction; it is free to cross into New Jersey, but motorists must pay when exiting the state.
The following table lists bridges with an Interstate Highway or U.S. Highway route, the four bridges to Philadelphia, and the six crossings to New York City: New Jersey Transit operates 247 bus routes throughout the state with 1785 buses under direct control and 327 buses leased to private operators.
On weekends, holidays, and from 11:00 pm to 5:00 am Monday to Friday, PATH combines the lines to operate two train services.
The Delaware River Port Authority operates the PATCO Speedline between Camden County in New Jersey and Center City, Philadelphia.
The PATCO Speedline operates 24 hours a day, although connecting rail facilities maintained by SEPTA and NJ Transit are closed during late night.
The Newark City Subway was opened in 1935, and was the sole remaining streetcar line when New Jersey Transit took operations in 1980.
The Hudson-Bergen Light Rail and the River Line were constructed by New Jersey Transit during the early 2000s using the rights-of-way of freight railroads.
The first Minimum Operating Segment of the Hudson-Bergen Light Rail was completed in 2002, and in 2006, service to its current northern terminus of Tonnele Avenue began.
The River Line uses lightweight diesel multiple units, running along trackage owned by Conrail between Trenton and Camden.
Amtrak operates intercity passenger rail service in New Jersey along the electrified Northeast Corridor between Boston and Washington.
Amtrak's high-speed Acela Express uses tilting technology to reach a maximum speed of 135 miles per hour (217 km/h)[27] between Washington and New York.
This is mainly because it is frequently used as an alternative stop for Amtrak passengers traveling in the New York area, as well as its status as the sole intercity rail station in heavily populated northeastern New Jersey.
The Delaware River Port Authority manages the RiverLink Ferry between the Camden waterfront and Penn's Landing in Philadelphia.
The remaining 20 percent of tonnage consists of through traffic that originates and terminates outside of the state (based on truck and rail data).
[35] New Jersey's freight rail system allows cost-effective shipment of goods and reduces traffic on highways.
Formerly a BP storage site for petroleum and chemicals, the facility is undergoing a renovation to relieve congestion from the ports of Camden.
In addition to domestic flights, Newark Liberty has extensive international service covering all inhabited continents except for Oceania.
Streamline, a subsidiary of Charter Air Transport, is prepared to start commercial service at Trenton-Mercer Airport on April 5[needs update].
