Brooklyn–Battery Tunnel Manhattan and Staten Island, and the X27, X28, X37, and X38 between Manhattan and Brooklyn. A vehicular tunnel under the East River between Manhattan and Brooklyn was proposed by the New York Board of Trade and Transportation in 1925, in response to growing truck traffic congestion in Lower Manhattan. The tunnel would have been located between the Manhattan Bridge and the Brooklyn Bridge. A tunnel that specifically connected the Battery in Manhattan with Red Hook in Brooklyn, passing underneath the East River and Governors Island south of both the Manhattan and Brooklyn Bridges, was first proposed by Brooklyn Borough president
Brooklyn Borough Hall in 1989. The Kings County Courthouse was built in 1868, turning this area – now known as Downtown Brooklyn – into a government center and busy area of commerce. In the 1940s, the Kings County Courthouse and other nearby buildings to the north were replaced by a complex of courthouses and a plaza in front of Borough Hall. A mall connects the building to Cadman Plaza Park.
