White Plains Road

White Plains Road is a major north-south thoroughfare which runs the length of the New York City borough of the Bronx. It runs from Castle Hill and Clason Point in the south to Wakefield in the north, where it crosses the city line and becomes West 1st Street of Mount Vernon, New York. The Bronx River Parkway lies to its west and parallels much of its route. Between Magenta Street & 217th Street, White Plains Road is very wide due to the presence of the Gun Hill Road station house in the road's median.
Historically, the route ran through an alignment through Mount Vernon by way of modern First Street, Lincoln Avenue, where it continued along modern North Columbus Ave. The route further continued with the current alignment Hussey Road across the Cross County Parkway, merging again with current North Columbus Avenue. These roads acquired their modern names around the end of the 19th century. Today at the Bronxville Village line, White Plains Road continues as New York State Route 22, to Broadway in White Plains where it terminates as Post Road.
