Queensboro Bridge
With the city takeover of the Brooklyn-Manhattan Transit Corporation's surface subsidiary, the Brooklyn and Queens Transit Corporation, on June 2, 1940, the city gained a large network of trolley and bus lines, covering all of Brooklyn and portions of Queens. On February 23, 1947, the Board of Transportation took over the Staten Island bus network of the Isle Transportation Company. Further acquisitions were made on March 30, 1947, with the North Shore Bus Company in Queens, and September 24, 1948, with the East Side Omnibus Corporation and Comprehensive Omnibus Corporation in Manhattan. The final Brooklyn trolleys were the Church Avenue Line and McDonald Avenue Line, discontinued on October 31, 1956, though the privately operated (by the Queensboro Bridge Railway) Queensboro Bridge Local remained until 1957.
