built include a line along Nostrand or Utica Avenues to Marine Park, as well as a subway line to Spring Creek. Brooklyn was once served by an extensive network of streetcars, but many were replaced by the public bus network that covers the entire borough. There is also daily express bus service into Manhattan. New York's famous yellow cabs also provide transportation in Brooklyn, although they are less numerous in the borough. There are three commuter rail stations in Brooklyn: East New York, Nostrand Avenue, and Atlantic Terminal, the terminus of the Atlantic Branch of the Long Island Rail Road. The terminal is near the Atlantic Avenue – Barclays Center subway station, with ten connecting subway services. In February 2015, Mayor Bill de Blasio announced that the city government would begin a citywide ferry service called NYC Ferry to extend ferry transportation to communities in the city that have been traditionally underserved by public transit. The ferry opened in May 2017, with the Bay Ridge ferry serving southwestern Brooklyn and the East River Ferry serving northwestern Brooklyn. A third route, the Rockaway ferry, makes one stop in the borough at Brooklyn Army Terminal. A streetcar line, the Brooklyn–Queens Connector, was proposed by the city in February 2016, with the planned timeline calling for service to begin around 2024. Roadways Most of the limited-access expressways and parkways are in the western and southern sections of Brooklyn, where the borough's two interstate highways are located; Interstate 278, which uses the Gowanus Expressway and the Brooklyn-Queens Expressway, traverses Sunset Park and Brooklyn Heights, while Interstate 478 is an unsigned route designation for the Brooklyn–Battery Tunnel, which connects to Manhattan. Other prominent roadways are the Prospect Expressway (New York State Route 27), the Belt Parkway, and the Jackie Robinson Parkway (formerly the Interborough Parkway). Planned expressways that were never built include the Bushwick Expressway, an extension of I-78 and the Cross-Brooklyn Expressway, I-878. Major thoroughfares include Atlantic Avenue, Fourth Avenue, 86th Street, Kings Highway, Bay Parkway, Ocean Parkway, Eastern Parkway, Linden Boulevard, McGuinness Boulevard, Flatbush Avenue, Pennsylvania Avenue, and Nostrand Avenue. Much of Brooklyn has only named streets, but Park Slope, Bay Ridge, Sunset Park, Bensonhurst, and Borough Park and the other western sections have numbered streets running approximately northwest to southeast, and numbered avenues going approximately northeast to southwest. East of Dahill Road, lettered avenues (like Avenue M) run east and west, and
