Bailey Bridge

Bailey Bridge, strong temporary or semi-permanent bridge constructed by a method suggested in 1941 by Sir Donald Bailey, then chief designer at the Royal Engineers Experimental Bridging Establishment in England. It consists of a series of mass-produced, lightweight girders that can be easily bolted together to produce the required length or to reinforce one another. Its immense flexibility and ease of construction made it immediately successful, particularly for military use. During World War II over 4,000 were built in Europe.
