Some road infrastructure projects at both ends of the tunnel were completed shortly after the tunnel opened. The first associated project to be completed was the Battery Park Underpass on the Manhattan side, which opened in April 1950. Two months later, officials opened a ramp on the Brooklyn side, which led from the southbound tunnel lanes to the northbound Brooklyn-Queens Expressway. The Battery Park Underpass was connected to the East River Drive elevated viaduct, and thus to the FDR Drive, in May 1954. The Brooklyn–Battery Tunnel project also entailed the restoration of Battery Park, which reopened in 1952 after a 12-year shutdown.
