Construction on the Brooklyn–Battery Tunnel started on October 28, 1940, but its completion was delayed due to World War II-related material shortages. This prompted city officials to reconsider plans for a tunnel. However, the public opposed the bridge plan, and the US Army Corps of Engineers (USACE) rejected the plan several times out of concern that the bridge would impede shipping access to the Brooklyn Navy Yard. After unsuccessful attempts to secure federal funds, New York City Parks Commissioner Robert Moses proposed a Brooklyn–Battery Bridge. The New York City Tunnel Authority, created in 1936, was tasked with constructing the tunnel. Official plans to build the tunnel were submitted in 1930 but were initially not carried out. Plans for the Brooklyn–Battery Tunnel date back to the 1920s. With a length of 9,117 feet (2,779 m), it is the longest continuous underwater vehicular tunnel in North America. Although it passes just offshore of Governors Island, the tunnel does not provide vehicular access to the island. The tunnel consists of twin tubes that each carry two traffic lanes under the mouth of the East River. Carey Tunnel and commonly referred to as the Battery Tunnel or Battery Park Tunnel, is a tolled tunnel in New York City that connects Red Hook in Brooklyn with the Battery in Manhattan. The Brooklyn–Battery Tunnel, officially the Hugh L. For the tunnel under Battery Park in Manhattan, see Battery Park Underpass.

The minimum height for inclusion in this list is 130 ft (40 m), which may be either the deck height or the clearance below depending on available references. For bridges that span tidal water, the clearance below is measured at the average high water level. ![]() Official figures for a bridge's height are often provided only for the clearance below, so those figures may be used instead of actual deck height measurements. A bridge's deck height is greater than its clearance below, which is measured from the bottom of the deck structure, with the difference being equal to the thickness of the deck structure at the point with the greatest clearance below. Height in this list refers to the distance from the bridge deck to the lowest point on the land, or the water surface, directly below. This is a list of the highest bridges in the United States by height over land or water. ![]() Royal Gorge Bridge, highest bridge in the United States
