In January 1936, the New York State Legislature created the New York City Tunnel Authority to oversee the construction of a tunnel between Midtown Manhattan and Queens. The bill also provided the authority with the power to build the Brooklyn-Manhattan tunnel if funds became available. By this time, the construction cost of the Brooklyn-Manhattan tunnel was now projected to be $58 million. Detailed plans for the tunnel were released in May 1936. The project now consisted of a $60.3 million twin-tube bore from Red Hook, Brooklyn, to the Battery, Manhattan, as well as a $2.3 million bridge over the Gowanus Canal. The city approved these plans in January 1936. One civic group wanted to plan for future traffic volumes, so it asked the city to conduct further studies of the Brooklyn-Manhattan tunnel project. The tunnel was officially renamed the "Brooklyn–Battery Tunnel" in July 1936. In November of that year, Brooklyn Borough President Raymond Ingersoll and New York City Parks commissioner Robert Moses revealed a plan to connect the Brooklyn–Battery Tunnel to Long Island's parkway system via a new Gowanus Parkway and Circumferential (Belt) Parkway. The planned tunnel was also part of the Regional Plan Association's proposed parkway system around New York City. The next month, the New York City Tunnel Authority advertised for bids to create test bores for the tunnel.
