About

The medium girder bridge (MGB) is lightweight, hand-built, bridging equipment. It can be built in various configurations to provide a full range of bridging capability for use both in the forward battle area and in the communications zone. Speed of erection by few Soldiers is its major characteristic. 1-2. The MGB parts are fabricated from a specially developed zinc, magnesium, and aluminum alloy (DGFVE 232A). This enables a lightweight, high strength bridge to be built. All except three parts weigh under 200 kg. Most parts can be handled easily by four Soldiers. The three heavier parts, used in limited quantities, are six-man loads. 1-3. The MGB is a two-girder, deck bridge. The two longitudinal girders, with deck units between, provide a 4.0m wide roadway. Girders of top panels can form a shallow, single-story configuration.
