Bridges
Bailey bridges are quickly installed and work quite well, I assume this is what they are going to put in temporarily. Most Bailey bridges are assembled and installed in a matter of days by a small crew. Common hand tools are utilized. All connections are pinned, bolted or clamped. No welding is necessary. Disassembly is similarly easy, and components can be stored in minimal space until reused. Bailey bridges are often installed by the cantilever launching method, in which the assembled bridge together with a “launching nose” is rolled out across the gap, without falsework or heavy equipment. The cantilever method allows bridges to be quickly erected over rivers or deep gorges. Additionally, some Bailey bridges may be hoisted into place by crane.
