Geography
White Horse is in southern Mercer County, with part of its southern border following Crosswicks Creek, the border with Burlington County to the south. Interstate 195 forms the remainder of the southern border of the community. Interstate 295 passes through the western part of the community. White Horse is bordered to the southeast by Yardville, and downtown Trenton is to the northwest. U.S. Route 206 passes through the center of White Horse, following Broad Street to the northwest toward Trenton. In the other direct, US 206 leads south to Bordentown.
According to the United States Census Bureau, the White Horse CDP has a total area of , including of land and of water (1.80%). 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 one 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 (now U.S. Route 1 Business, U.S. Route 206, and Route 31) 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.<br> 1950 1960 1970<br> 1980 1990 2000<br> 2010 2020
