The New Jersey Turnpike (NJTP), known colloquially as "the Turnpike", 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 in November 1951, between its southern terminus and exit 10.
