The PABT, opened in 1950 between Eighth and Ninth 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. Since then, the terminal has reached peak hour capacity, leading to congestion and overflow on local streets. It does not allow for layover parking; hence, buses are required to use local streets or lots, or return through the tunnel empty. The PANYNJ has been unsuccessful in its attempts to expand passenger facilities through public private partnership, and in 2011 it delayed construction of a bus depot annex, citing budgetary constraints. In June 2013, it commissioned an 18-month study that would consider options for reconfiguration, expansion, and replacement of the terminal.
