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.

The Airport Circle is a traffic circle in Pennsauken Township, New Jersey, United States. It is located at the intersection of Route 38, U.S. Route 30 (US 30), and US 130, close to the Camden border. South of the circle, US 30 and US 130 run concurrently until they reach the former Collingswood Circle in Collingswood. The Airport Circle opened in 1927 and is the first of is kind in the United States. It is named for Camden Central Airport whose terminal building was located beside the circle, to the south-east. The circle has been modified to include traffic lights and ramps to help ease traffic congestion.
