Radburn, New Jersey, was founded in 1929 as an early planned community using a superblock design.
The community was developed by the City Housing Corporation and planned by Clarence Stein and Henry Wright. Its layout separated pedestrian paths from major roads and grouped homes around shared green spaces, ideas influenced by the Garden City movement.
Radburn's superblocks were larger than conventional city blocks, allowing internal parks and walkways while keeping through traffic on perimeter streets. The plan also introduced features intended to support neighborhood life, including communal open space and carefully arranged housing groups.
Radburn is sometimes described as the first community designed around the automobile, but that wording can mislead: its planners tried to accommodate cars while protecting pedestrians. Its planning ideas influenced later suburban developments in the United States and elsewhere.
