In 1936, the plan for a Narrows crossing was brought up again when now-New York City Mayor La Guardia gained authorization to petition the U.S. Congress for a bridge across the Narrows. Under the new plan, the proposed bridge would charge tolls for motorists, and its $50million cost would be paid off using federal bonds. LaGuardia preferred a tunnel instead, and so the next year he requested the New York City Tunnel Authority to review the feasibility of such a crossing. The New York City Planning Commission was amenable to constructing either a bridge or a tunnel across the Narrows, and in 1939, put forth a plan to expand New York City's highway system. In March of the same year, as a bill for the Battery Bridge was being passed, Staten Island state legislators added a last-minute amendment to the bill, providing for a Narrows bridge. The Narrows crossing was not included in the final version of the Planning Commission's plan, which was approved in 1941.
