New Jersey State Highway Routes

Route 18 is a 42.8-mile-long (68.9 km) state highway in the US state of New Jersey. It begins at an intersection with Route 138 in Wall and ends at Interstate 287 (I-287) in Piscataway. Much of the route is a limited-access freeway, including the entire portion in Monmouth County and much of the northern end through New Brunswick and Piscataway. The remainder of the route is a multi-lane divided highway. Route 18 was formerly designated as Route S28, a prefixed spur of State Highway Route 28 through Middlesex and Monmouth counties. The designation, assigned in the 1927 renumbering, remained until a second renumbering in 1953. At that point, Route 18 was designated onto the alignment.

The route originally ended at Route 27 at the border between Highland Park and New Brunswick, but was extended northward to then-County Route 514 Spur (CR 514 Spur), now CR 622, in 1983. The freeway through New Brunswick was constructed during the 1980s over the Delaware and Raritan Canal. Route 18 was further extended to Hoes Lane in Piscataway in 2004 and presently ends at I-287 in Piscataway. The route south of exit 6A in Wall was also originally intended to extend to the Brielle Circle and terminate at Route 34, Route 35, and Route 70 but there are no plans to do so currently.
