Victoria Bridge in Bath, England, was built in 1836 across the River Avon. The bridge has been recognised as a Grade II * listed building. The bridge is an important example of a suspension bridge which initially carried horses and carts but later carried cyclists and pedestrians until its closure on safety grounds in 2011. ==Construction== The cable-stayed double cantilever bridge, built by Motley and Dredge, has a span of with the chains slung from Bath stone towers. The road deck is joined to the chains by iron eyebars, which, unusually, are not vertical.〔 James Dredge who was a brewer in Bath designed the bridge to carry beer from his brewery across the river without using a ferry or having to detour through the city centre.〔 Construction cost £1,760. He patented the 'Taper principle' based on using chains rather than cables, as is now more common in suspension bridges.〔(【引用サイトリンク】url=http://www.sabre-roads.org.uk/wiki/index.php?title=James_Dredges_Suspension_Bridges )〕 Dredge's bridge design was considered "a very significant yet relatively short-lived phase in suspension bridge development". The main span chains have 155 links each of which is long and supports two wrought iron hangers. The deck is made of wooden planks.〔 Initially the bridge was used for horse-drawn carts but later only carried bicycles and pedestrians. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Victoria Bridge, Bath」の詳細全文を読む スポンサード リンク
