List of Traffic Circles in New Jersey

This is a list of traffic circles in New Jersey. The U.S. state of New Jersey at one point had a total of 101 traffic circles, 44 of which were part of state roads. However, the number has shrunk as traffic circles have been phased out by the New Jersey Department of Transportation. In the 1920s and 1930s, New Jersey felt that traffic circles were an efficient way for moving traffic through three or more intersecting roads. Built in 1925, the first traffic circle in New Jersey was the Airport Circle in Pennsauken. Many of these interchanges are rotaries in design, as opposed to the more successful modern roundabout.

As suburban and rural populations grew New Jersey's traffic circles became outdated. The increased number of drivers on the roads resulted in traffic circles being more likely to hinder traffic than help it. Increased number of vehicles and faster traffic speeds made traffic circles more dangerous and accidents common. Many traffic circles became notorious for having frequent accidents and being confusing, especially for non-locals. The confusion frequently is the result of ignorance of the elementary traffic law which governs right of way while using traffic circles, NJSA 39:4-90, "The driver of a vehicle approaching an intersection shall yield the right of way to a vehicle which has entered the intersection. When 2 vehicles enter an intersection at the same time the driver of the vehicle on the left shall yield the right of way to the driver of the vehicle on the right.". Since a circle is comprised as a series of uncontrolled intersections, the driver to the right (entering the circle) has the right of way. Starting around the 1970s, the New Jersey Department of Transportation began phasing out traffic circles. Common methods of eliminating traffic circles are building a road through the circle, adding traffic lights, and the use of grade separation.
