NJ 18 is a major highway in New Jersey, extending from NJ 138 to Rutgers University in Piscataway. The southern portion is a limited-access highway known as the Monmouth Freeway. Further north, it has a combination of grade-separated interchanges and traffic lights. The northernmost section, known as Memorial Parkway, is a limited-access highway again. The entire length is a large divided highway. NJ 18 was planned to extend several miles south of where it currently begins to the junction of NJ 34, NJ 35, and NJ 70. Therefore, the exit numbers of the Monmouth Freeway begin at 6.
Construction work is currently in progress to upgrade Hoes Lane and Centennial Avenue in Piscataway. When the work is done, NJ 18 will be extended along these roadways to end at the Middlesex Freeway (I-287).
