The New Jersey Turnpike (NJTP) is a system of controlled-access highways in the U.S. state of New Jersey, maintained by the New Jersey Turnpike Authority (NJTA). The 117.20-mile (188.62 km) mainline's southern terminus is at the interchange with U.S. Route 130 (US 130) and Route 49, where the split of Interstate 295 (I-295) and US 40 occurs, near the border of Pennsville and Carneys Point townships in Salem County, one mile (1.6 km) east of the Delaware Memorial Bridge. Its northern terminus is at US 46 in Ridgefield Park, Bergen County. Construction of the mainline from concept to completion took 23 months, from 1950 to 1952. It was officially opened to traffic on November 5, 1951, between its southern terminus and exit 10.The turnpike is a major thoroughfare providing access to various localities in New Jersey, as well as Delaware, Pennsylvania, and New York. The toll road provides a direct bypass southeast of Philadelphia for long distance travelers between New York and Washington. According to the International Bridge, Tunnel and Turnpike Association, the turnpike is the nation's sixth-busiest toll road and is one of the most heavily traveled highways in the United States.The northern part of the mainline turnpike, along with the entirety of its extensions and spurs, is part of the Interstate Highway System, designated as I-95 between exit 6 and its northern end. South of exit 6, it has the unsigned Route 700 designation. There are three extensions and two spurs, including the Newark Bay Extension at exit 14, which carries I-78; the Pennsylvania Turnpike Extension (officially the Pearl Harbor Memorial Turnpike Extension) at exit 6 which carries I-95 off the mainline turnpike; the Eastern Spur and the Western Spur which split traffic between Newark and Ridgefield; and the I-95 Extension which continues the mainline to the George Washington Bridge. All segments except for the I-95 Extension are tolled.
The route is divided into four roadways between exit 6 and exit 14. The inner lanes are normally restricted to carrying only cars, with the outer lanes for cars, trucks, and buses. The turnpike has 12-foot-wide (3.7 m) lanes, 10-foot-wide (3.0 m) shoulders and 13 rest areas named after notable New Jersey residents. The Interstate Highway System took some of its design guidelines from those for the turnpike. The turnpike is considered iconic in popular culture having been referenced in music, film, and television.
