White Horse Circle
White Horse Circle is a traffic circle locally known by name, in the southwest part of White Horse. Up until 2018 it was not a true traffic circle, because it was bisected by northbound U.S. Route 206, which made a left turn in the circle. This intersection connects South Broad Street, White Horse-Mercerville Road and Bordentown Road. Only Route 533 had a stop sign at the circle, while Route 524 and the southern part of Route 206 have traffic signals some distance from the circle. To allow cars to move in a safe fashion, there were six yield-signed road segments allowing cars to get to Route 206 and from the highway to Route 533. Route 206, when the light allowed, had no yield sign restrictions. Since the completion of Interstate 195 and Interstate 295, which intersect southwest of the circle, much of the traffic that would have passed through the circle is able to use the wider, faster freeways, reducing the traffic load at the circle. Hamilton Township approved a construction project under which the modifications at the circle were completed by 2018, at a site that the township's engineer described as having an average of an accident a week. The new circle operates as a roundabout with two concentric lanes and many arrows to help drivers navigate the circle. The biggest change was the new requirement to yield to traffic in the circle, rather than yielding to traffic on the major roads. Accidents have decreased since this new roundabout was finished. In the 1927 New Jersey state highway renumbering, Route 37 was legislated to run from Route 27 and Route 30 in Trenton continuing through the White Horse Circle and on to Seaside Heights. The western end of Route 37 was once planned to be at White Horse Circle, though that section of the planned route was eventually built as Interstate 195, with other portions returned to the counties as part of Route 524. A tall statue of a white horse was constructed on the circle in 2010, commemorating the local tradition that George Washington rode through the area on a white horse while traveling to New York City in 1789.
