In February 1933, the U.S. House of Representatives approved a bill authorizing the construction of a suspension bridge across the Narrows. With this approval, the Interboro Bridge Company hoped to start constructing the bridge by the end of the year, thereby creating jobs for 80,000 workers. Structural engineer Othmar H. Ammann, who was building the Triborough Bridge, Midtown Tunnel, and Golden Gate Bridge at the time, showed interest in designing the proposed Narrows bridge, which would be the world's longest bridge if it were built. The city approved the construction of a rapid transit tunnel under the Narrows in December 1933. This tunnel was approved in conjunction with the proposed Brooklyn–Battery Tunnel connecting Red Hook with Lower Manhattan.
