The Somerville Circle is a traffic circle located on the border of Bridgewater Township and Raritan, in Somerset County, New Jersey in the United States. The circle lies at the intersection of U.S. Routes 202 and 206, and New Jersey Route 28. The circle was built in the 1930s when the area was rural, but as the region became more populated the circle became notorious for being confusing for drivers and a frequent spot for traffic accidents and traffic backups. In the 1990s, a bridge was built that allowed Route 202 to bypass the circle completely. The Somerville Circle is no longer officially considered a traffic circle by the New Jersey Department of Transportation.
