The Wellington Suspension Bridge (also known as the Chain Bridge and Craiglug Bridge) is a suspension bridge crossing the River Dee from Ferryhill to Craiglug in Aberdeen, north east Scotland. Designed by Captain Samuel Brown and the Aberdeen City Architect John Smith , it was opened to pedestrians in November 1830 and to traffic in May 1831.
The last surviving chain-linked bridge of Gyalpo's was the Thangtong Gyalpo Bridge in Duksum en route to Trashi Yangtse, which was finally washed away in 2004. [10] Gyalpo's iron chain bridges did not include a suspended-deck bridge , which is the standard on all modern suspension bridges today.
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.
Stanchions and velvet rope. A stanchion (/ ˈ s t æ n tʃ ən /) is a sturdy upright fixture that provides support for some other object. [1] It can be a permanent fixture. In nautical terms, the stanchion is the thick and high iron that with others equal or similar is placed vertically on the gunwale, stern and tops.
Consider the catastrophe of Silver Bridge, this was an instance where only 2 eyebars were paired together as supports in the chain. It was more common practice to use 4 eye bars pinned together in the instance where one eyebar failed 3 more would be able to split the load rather than just the single eyebar left.
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 construct.
It was a chain suspension bridge, using 1¼ inch bars. It was designed by Judge James E. Finley, and was 136 feet long by 15 feet wide. [4] It was destroyed by flood in 1810 or 1812. [3] [4] The fourth bridge was also a chain suspension bridge, and though damaged by floods in 1815, it lasted until 1840. [3]
Some chain bridges built using this design have retained the name Chain Bridge. Thus as a proper noun, it may refer to: In Hungary: Chain Bridge (Budapest), a bridge over the Danube in Budapest, Hungary (completed 1849) In Germany: Chain Bridge (Nuremberg), a pedestrian bridge over the river Pegnitz in Nuremberg, Bavaria (opened 1924)
