Travel directions

The highway begins in Belmar, a suburb 100 kilometers from Manhattan, at the interchange with Interstate 195, which leads to Trenton. The road has 2×2 lanes and runs through the coastal towns to the north. The area surrounding the highway is often densely wooded, so that little is seen of the enormous urban mass. At Long Branch one crosses the Garden State Parkway, the turnpikealong the New Jersey coast. The SR-18 then curves to the west, temporarily through a slightly less densely built-up area, because a nature reserve and military base is located here. You pass the town of Freehold, which has a population of 32,000, and is completely absorbed in the immense urbanity of central New Jersey. After the intersection with US 9, the highway section ends, and the road continues as a 2×2 main road with at-grade intersections. Large connections are on the same level. Closer to New Brunswick, the road widens to 2×3 lanes. One then crosses Interstate 95, also called the New Jersey Turnpike. Then you cross US 1, a secondary highway parallel to I-95. The road then forms an expresswaythrough New Brunswick on the Raritan River. In Piscataway the road ends on the regular street network of New Brunswick.


The highway was developed as an east-west route between New Brunswick and the coastal region around Belmar. Construction started in the mid-1960s, but it was quite stiff. Much of the route was not completed until 1979, with the exception of a missing link in Neptune, which was not opened until 1987 and 1991. Then the large Eatontown Interchange opened with the Garden State Parkway.

In 1962 there were plans to build a highway from US 1 in New Brunswick to US 22 in Bound Brook, a 15-kilometer-long 2×2 lane highway. Part of this route has actually been constructed, with construction beginning as early as the late 1960s, but opening was delayed until the early 1980s due to new environmental laws that delayed construction by a decade. The expressway through New Brunswick finally opened to traffic in 1983. In 2004, an extension opened to Piscataway. However, the route to I-287 has not been constructed. Between Piscataway and Bound Brook, I-287 now serves as the highway planned in 1962.
