How much did Brooklyn–Battery Tunnel cost to build?
The Brooklyn–Battery Tunnel, officially the Hugh L. Carey Tunnel, links Lower Manhattan and Brooklyn beneath New York Harbor. Each of its two 9,117-foot (2,779-metre) tubes carries two traffic lanes. Construction started in October 1940, paused during World War II and resumed in 1946; the tunnel opened to traffic on 25 May 1950. A contemporary interview with the operating authority described the original tunnel-only estimate as about $57 million and its 1947 estimate as $70 million, explicitly excluding approach roads. New York City's archives describe a roughly $60 million city proposal in 1936. The Federal Highway Administration describes the completed 1950 tunnel as an $80 million project. These historic nominal-dollar figures refer to different stages and sometimes different scope; later parking, approach roads and tunnel upgrades are not silently included in the gameplay answer.
