The cancellation of plans for the Narrows tunnel brought a resurgence of proposals for a bridge across the Narrows. In September 1947, Robert Moses, the chairman of the Triborough Bridge and Tunnel Authority (TBTA), announced that the city was going to ask the War Department for permission to build a bridge across the Narrows. Moses had previously created a feasibility study for a Narrows tunnel, finding that it would be much cheaper to build a bridge. Moses and Mayor William O'Dwyer both supported the Narrows Bridge plan, which was still being referred to as "Liberty Bridge". The city submitted its request to the War Department in July 1948, and a commission composed of three United States Armed Forces branches was convened to solicit the public's opinions on the proposed span.
