The bridge may be stiffened by the addition of cables that do not bear the primary structural or live loads and so may be relatively light. These also add stability in wind. An example is the 220-meter-long (720 ft) bridge across the river Drac at Lac de Monteynard-Avignonet: this bridge has stabilizing cables below and to the side of the deck.
The center span between the two suspension towers is 1,380 feet (421 m) long, [16] [17] and the side spans between the suspension towers and the anchorages are each 700 feet (213 m) long. [16] The total length of the bridge is 2,780 feet (847 m), and the deck is 98 feet (30 m) wide. [16]
The moving bridge had two bascule leaves, each 48 feet (15 m) long that were connected by a 69 feet (21 m) long deck-girder approach, for a total overall length of 372 feet (113 m). [6] The girders were 40 feet (12 m) in width; which were wider than the 37.5 feet (11.4 m) bascules. [6]
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.

Kingston–Port Ewen Suspension Bridge: Maintained by: New York State Department of Transportation: ID number: 1007350: Characteristics; Design: Wire cable Suspension bridge: Total length: 2 side spans of 176.25 feet (54 m) each, anchorages, total length 1,145 ft (349 m) Width: 2 lanes plus walkway, 37 feet (11 m) Longest span: 705 feet (215 m ...
It's called Peak Walk at the Glacier 3,000 Resort in the Swiss Alps, and it's the world's first suspension bridge to ever 31 inches wide. 9,800 feet up. That's a bridge
The high number of complex moving parts – fourteen hydraulic rams, numerous precision bearings, and an underground machinery chamber to provide the required oil pressure – can be seen as an example of overengineering, and has led to maintenance failures where the bridge is unable to move for significant periods of time.
The bridge's 58 anchors all feature 3-inch-thick (7.6 cm), 1,000-foot-long (300 m) steel cables and are divided into three types: 45 587-short-ton (533 t) fluke anchors used in softer soils deep in the lakebed; eight 107-short-ton (97 t) gravity anchors used in solid soils nearer to the shore; and five 10-foot-diameter (3.0 m), 79-to-92-foot ...
