High Quality Content by WIKIPEDIA articles! Route 7 is a state highway in the northern part of New Jersey in the United States. It has two sections, an east–west alignment running from U.S. Route 1/9 Truck in Jersey City to Route 21 in Belleville, and a north–south alignment running from the Newark/Belleville to the Nutley/Clifton border, and is one of two state highways in New Jersey to have an intentional discontinuity (New Jersey Route 440 is the other). The New Jersey Department of Transportation lists Route 7 as a single north–south highway with a small gap between the alignments. The entire highway has a combined length of 10.16 mi (16.35 km).
