Portable Prefabricated Truss Bridge/Bailey Bridge

The Bailey Bridge is a type of portable, pre-fabricated,truss bridge.It was developed by the British during World War II for military use and saw extensive use by British,Canadian and US military engineering units
A Bailey bridge has the advantages of requiring no special tools or heavy equipment to assemble. The wood and steel bridge elements were small and light enough to be carried in trucks and lifted into place by hand,without requiring the use of a crane. The bridges were strong enough to carry tanks.Bailey bridges continue to be used extensive in civil engineering construction projects and to provide temporary crossings for foot and vehicle traffic.
 

Description: Bailey bridges are built on site from a pre-engineered system of ready-to-assemble components. Utilizing standardized prefabricated components, Bailey bridges can be built to match a wide range of vehicular bridging applications. Because of their excellent versatility and overall value, thousands of Bailey bridges have been installed throughout the world.

For many ways  use, typical Bailey bridge clear spans range from 20 ft to 200 ft. Multiple-span bridges of any length are possible by incorporating intermediate supporting piers.
The Bailey Bridge is a safe, proven answer to diverting or detouring traffic for construction. A perfect solution, a temporary Bailey Bridge detour for the contractor:

Speed construction - pre-engineered stocked componentsSafety - time-tested performanceModular - fast installation and removalVersatility - 10' multiple bays use the same partsCost effective to own and re-use in different length bridgesDamaged parts can be easily and quickly replaced from stock
