Parts of the bridge
The basic Bailey bridge is made up of three main parts, the floor,
the stringers and the side panels. The floor of the bridge is made
up of a number of 19-foot-wide transoms (5.8 m) that run across the
bridge. Across the bottom of these, forming a square, are
10-foot-long stringers (3.0 m). The bridge's strength is provided
by the panels on the sides. The panels are 10-foot-long (3.0 m),
5-foot-high (1.5 m), cross-braced rectangles. Each weighs 570
pounds (260 kg), and can be lifted by six men.

structural steel that is right the first time, helping you avoid
costly construction delays.
Finally
The success of the Bailey bridge was due to the simplicity of the
fabrication and assembly of its modular components, combined with
the ability to erect and deploy sections with a minimum of
assistance from heavy equipment. Many previous designs for military
bridges required cranes to lift the pre-assembled bridge and lower
it into place. The Bailey parts were made of standard steel alloys,
and were simple enough that parts made at a number of different
factories could be completely interchangeable. Each individual part
could be carried by a small number of men, enabling army engineers
to move more easily and more quickly than before, in preparing the
way for troops and materiel advancing behind them. Finally, the
modular design allowed engineers to build each bridge to be as long
and as strong as needed, doubling or tripling up on the supportive
side panels, or on the roadbed sections.
