Brooklyn features extensive public transit. Nineteen New York City Subway services, including the Franklin Avenue Shuttle, traverse the borough. Approximately 92.8% of Brooklyn residents traveling to Manhattan use the subway, despite the fact that some neighborhoods like Flatlands and Marine Park are poorly served by subway service. Major stations, out of the 170 currently in Brooklyn, include: Proposed New York City Subway lines never 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, many of which were replaced by
Brooklyn Bridge series, historical walking tours, information tents, a series of lectures and readings, a bicycle tour of Brooklyn, a miniature golf course featuring Brooklyn icons, and other musical and dance performances. Just before the anniversary celebrations, artist Paul St George installed the Telectroscope, a video link between New York City and London, on the Brooklyn side of the bridge. The installation lasted for a few weeks and permitted viewers in New York City to see people looking into a matching telectroscope near London's Tower Bridge. A newly renovated pedestrian connection to the DUMBO neighborhood was also unveiled before the anniversary celebrations.
