Such long bridges required support from either piers or pontoons. [35], The longest Bailey bridge was put into service in October 1975. It is also easier to mount safety rails which are usually placed along the outside of the bridge. The materials to build a truss bridge are minimal, and every single bit is used very efficiently. Another disadvantage would be beam bridges may start to sag due to excessive loads. Their flexibility makes them ideal for long spans, but their strength does diminish when the span is too great. Theyre just beams with an I- or H-shaped cross-section. [27] In all, over 600 firms were involved in the making of over 200 miles of bridges composing of 500,000 tons, or 700,000 panels of bridging during the war. A Bailey bridge and its construction were prominently featured in the 1977 film A Bridge Too Far. [10] The design was tested at the Experimental Bridging Establishment (EBE), in Christchurch, Dorset,[7][11] with several parts from Braithwaite & Co.,[12] beginning in December 1940 and ending in 1941. In 2018, the Indian Army erected three new footbridges at Elphinstone Road, a commuter railway station in Mumbai, and at Currey Road and Ambivli. Answer: The advantages are obvious.

A Bailey bridge is a type of portable, pre-fabricated, truss bridge. The first Bailey bridge built under fire was constructed at Leonforte by members of the 3rd Field Company, Royal Canadian Engineers. Each individual part could be carried by a small number of men, enabling army engineers to move more easily and quickly, in preparing the way for troops and matriel advancing behind them. [3] Transoms rest on the lower chord of the panels, and clamps hold them together. There are many different types of wooden beam bridges ranging from short spans to long spans. Each unit constructed in this fashion creates a single 10-foot-long (3.0 metres) section of bridge, with a 12-foot-wide (3.7 metres) roadbed.

A Bailey bridge has the advantages of requiring no special tools or heavy equipment to assemble. Feiyunjiang Bridge: Span: 2,956 m (9,698 feet).
