Suspension bridge types other end tied into a conventional cable stay. The underspanned portion of the span is long and has three vertical members. The Akashi Kaikyō Bridge, one of the longest suspension bridges in the world, is a suspended-deck suspension bridge with a stiff truss girder deck. Its main span is 1,991 meters long. Unlike many other types of bridge, suspension bridges often can be built without use of falsework. In many cases, the main cables are constructed first, then the deck is added. This often involves the use of a pilot cable. For details of their construction methods, see the articles
All-dielectric self-supporting cable suspension type, only holding the weight of a span with tension transmitted through the next span of cable. Reinforcing rods are used on either side of a support and at dead-ends. Wind-induced aeolian vibration is a factor since ADSS cables have light weight, relatively high tension, and little self-damping. Anti-vibration dampers are installed on each span near the support points. Accessories must not be clamped directly to the cable but instead over reinforcing rods, to protect the cable from electrical and mechanical damage. Termination boxes are used to enclose and protect splices between the ADSS cable and "inside plant" cable
