[1]  [DOC] The Port Authority Bus Terminal (PABT) is the main gateway for interstate buses into Manhattan in New York City. It is owned and operated by the Port Authority of New York and New Jersey (PANYNJ). Colloquially called the Port Authority, the bus terminal is located in Midtown at 625 Eighth Avenue between 40th Street and 42nd Street, one block east of the Lincoln Tunnel and one block west of Times Square. The PABT, opened in 1950 between 8th and 9th Avenues and 40th and 41st Streets, was built to consolidate the many different private terminals spread across Midtown Manhattan. A second wing extending to 42nd Street was added in 1979. It is one of three bus terminals operated by the PANYNJ, the others being the George Washington Bridge Bus Station in Upper Manhattan and the Journal Square Transportation Center in Jersey City.
