Menai Bridge
Menai BridgeThe Menai Bridge from the Anglesey side, after an illustration by Henry Gastineau for Wales Illustrated, London, 1830.
Menai Bridge, suspension bridge spanning the Menai Strait from Bangor, Wales, to the Isle of Anglesey, a distance of 176 metres (580 feet). Designed and built (1819β26) by Thomas Telford, it was the first important modern suspension bridge. The deck, designed for two carriageways, was suspended by iron chains from masonry towers at either end. Sixteen chain cables were each composed of 935 iron bars, a total of 2,000 tons of wrought iron. Though damaged by storms, the bridge survived because of the addition of transverse bracing and trussed railings. In 1939, to accommodate increased automobile traffic, the chains were replaced by steel cables. See also Britannia Bridge.
