Suspension bridge nearby Chain Bridge at Falls of Schuylkill (1808). The footbridge's span was 124 m, although its deck was only 0.45 m wide. Development of wire-cable suspension bridges dates to the temporary simple suspension bridge at Annonay built by Marc Seguin and his brothers in 1822. It spanned only 18 m. The first permanent wire cable suspension bridge was Guillaume Henri Dufour's Saint Antoine Bridge in Geneva of 1823, with two 40 m spans. The first with cables assembled in mid-air in the modern method was Joseph Chaley's Grand Pont Suspendu in Fribourg, in 1834. In the United States, the first
Cable fairing slide down the cable (until they “stack” at the aft end) without the use of the anti-stacking rings. Cable fairing A cable fairing is a structure attached to a towed cable designed to streamline the flow around the cable, primarily in marine environments. Cables are faired primarily for two reasons: (1) to reduce normal drag and thus achieve more depth for a given cable scope and speed; and (2) to eliminate cable vibration caused by vortex shedding, commonly known as cable strum. There are several major types of cable fairing: All cables (faired or unfaired) have hydrodynamic loading functions. These
