The clearance below required under bridges for the largest ships—container ships, ocean liners and cruise ships—is around 220 feet (67 m) so there are often bridges with approximately that height located in coastal cities with bays or inlets, such as New York City's Verrazzano-Narrows Bridge and San Francisco's Golden Gate Bridge.

The bridge opened on November 1, 1957, [10] connecting two peninsulas linked for decades by ferries. At the time, the bridge was formally dedicated as the "world's longest suspension bridge between anchorages", allowing a superlative comparison to the Golden Gate Bridge, which has a longer center span between towers, and the San Francisco–Oakland Bay Bridge, which has an anchorage in the middle.
This bridge spans a deep river gorge. The bridge's two towers, built on either rim of the gorge, are 269 m (883 ft) tall, but due to the depth of the river gorge, the deck height of the Duge Bridge is 565 m (1,854 ft). The Millau Viaduct is a cable-stayed bridge that is both tall (in structural height) and high (in deck height). The tallest ...
The world's longest suspension bridges are listed according to the length of their main span (i.e., the length of suspended roadway between the bridge's towers). The length of the main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge.

The NBI can classify bridges as "structurally deficient," which means that the condition of the bridge includes a significant defect, which often means that speed or weight limits must be put on the bridge to ensure safety; a rating of 4 or lower on any of items 58, 59, 60, or 62 (deck, superstructure, substructure, and culverts, respectively ...
Due to its height, the bridge is a noteworthy suicide site. As of February 2024 [update] , there have been 102 suicides since the bridge's construction. [ 7 ] As part of the bridge's 2011–2015 renovations, a 6 + 1 ⁄ 2 -foot-tall (2.0 m) pedestrian barrier was installed to prevent further attempts.
