HISTORY AND DESCRIPTION: At the outset of world war II, the United States (US) Army sought

a versatile bridge that could span a variety of gaps and be quickly assembled by manpower alone. For

this reason, we adopted the design from the British prefabricated Bailey bridge, US nomenclature M1.

We revised the design to provide a greater roadway width of 121/2 feet and designated it the Panel

Bridge, Bailey M2. The Bailey bridge is a through-type bridge, the roadway being carried between two

main girders. The trusses in each girder are formed by 10-foot panels pinned end to end. The main

girders on each side of the bridge can be assembled in multiple widths and heights to provide added

strength and/or length of span. The Bailey bridge system is highly labor-intensive but also a highly

versatile system. Some of the different types of structures that can be constructed are two lane,

through-type bridge; deck type bridge; bridge on piers; railway bridge; and floating bridges. In some

case, because it can be assembled in multiple heights and widths, it is the only tactical bridge suitablefor long spans and heavy loads.

EQUIPMENT CHARACTERISTICS AND CAPABILITIES: The Medium Girder Bridge (MGB) is a

two girder deck bridge. The wide upper surfaces of the girders, and deck units laid between them form a

roadway 13ft 2in (4.0m) wide. The girders can be constructed in two forms: a shallow single story

construction or a deeper double story construction. The double story can be reinforced by adding

components of the Link Reinforcement Set (LRS) this permits longer Military Load Class (MLC) 70

bridges can be constructed
