   Falsework required. Usually. A self-anchored suspension bridge is a suspension bridge type in which the main cables attach to the ends of the deck, rather than directly to the ground or via large anchorages. [ 1] The design is well-suited for construction atop elevated piers, or in areas of unstable soils where anchorages would be difficult to ...

   High piers. The total height of the structure is generally between 1.5 a and 2.5 a. [7] The arches are semicircular, and their thickness T depends both on the span a of the arches and on the height H of the structure: [7] If H = 2.5 a, T = 0.1 a + 0.04H. If H < 2.5 a, T = 0.125 a + 0.04H. However, if the span a is small (a<8 m), it is ...

   The main suspension span of the bridge is 10.5 feet (3.2 m) wide and 272 feet (83 m) long, with two wooden approach ramps that bring the total length to 334 feet (102 m). Two pairs of main cables are anchored by large concrete blocks in the ground. The secondary suspension cables are attached to floor beams with eyebolt and ring connections.
