Smoot, who in October 1958 lay down repeatedly on the Harvard Bridge between Boston and Cambridge, Massachusetts, so that his fraternity brothers could use his height to measure the length of the bridge.
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.

Cantilevered high over the Tarn gorge in southern France, and yawning 2,460 meters (8,070 feet) in length, the Millau Viaduct is the world’s tallest bridge, with a structural height of 336.4 ...
Including approaches, the Brooklyn Bridge is a total of 6,016 feet (1,834 m) long [2] [3] [4] when measured between the curbs at Park Row in Manhattan and Sands Street in Brooklyn.

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 new bridge took five years to build, was 19 months late and ran $20 million over budget when it opened in 1987. But experts say it's better to look to more recent bridge disasters for a sense ...
