Bailey System Steel Truss Bridge Simple Structure Military Bridge
Ease of Assembly and Installation
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.
Bailey bridge components can be assembled in seven different
configurations to efficiently accommodate a wide range of span and
capacity requirements. Panels, the primary Bailey components, are
pinned together at the job site to make girders of any length.
Various girder strengths are achieved by assembling either a single
row of panels, or two or three rows side-by-side. Panels may also
be stacked in double-story height for further increase strength.
For greatest strength, longer spans may be chord-reinforced.
For highway 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
