About Bronx County

Bronx County was the first county in the United States to have a population of over one million residents, and it remains New York City's third-most populous county.The Bronx is divided by the Bronx River into a hillier section in the west, and a flatter eastern section. East and west street names are divided by Jerome Avenue—the continuation of Manhattan's Fifth Avenue; while Grand Concourse (originally Mount Morris Park West) divides street names east–west between Jerome Avenue to its south, Mosholu Parkway along its north side, Walton Avenue on both sides below Fordham Road; then Boston Road above Fordham Road until East 205th Street at Van Cortlandt Park South. The major cross streets typically run from Broadway or Columbus Circle through Central Park North or South (parallel with Manhattan), up to Mosholu/Jerome Avenues (parallel with Macombs Dam Bridge).
