Where Third Avenue, carried over from Manhattan, crosses East 138th Street in Mott Haven.
Third Avenue leaves Manhattan, crosses the Harlem River on the Third Avenue Bridge and continues through the Bronx to Fordham Road. Manhattan’s street numbering was carried into the Bronx, though haphazardly. East 138th Street is the main east–west street of Mott Haven, named after Jordan Mott, who bought land here for his iron works in 1849.
