The B15 bus route heads south through Bedford–Stuyvesant along Marcus Garvey Boulevard (southbound) and Lewis Avenue (northbound). After crossing Fulton Street, buses use a number of streets through Crown Heights and Ocean Hill, eventually turning south on Ralph Avenue and southeast on East 98th Street. In Brownsville and East New York, buses head east on Hegeman Avenue and New Lots Avenue, then south to Linden Boulevard and merging onto Conduit Avenue after entering Queens. B15 buses then serve several areas of JFK Airport and end at Terminal 5. Between the Brooklyn-Queens border and JFK Airport, B15 buses run non-stop.
