Southern Boulevard is a street in the Bronx, New York City. It stretches from 142nd Street in the south to White Plains Road in the north. Until 2011, the portion north of Fordham Road, adjacent to the New York Botanical Garden, was also named Dr. Theodore L. Kazimiroff Boulevard. The name of Kazimiroff, a Bronx historian, was taken off of the street signs of Southern Boulevard because the New York City Department of Transportation believed that Kazimiroff's name was unpopular with locals, citing the fact that many people did not know where Kazimiroff Boulevard was.
The 2 5 trains run directly above Southern Boulevard from Simpson Street to 174th Street. The 6 <6> trains also run under Southern Boulevard from East 149th Street to Hunts Point Avenue.
