Heavy Girder Over Bridge The Heavy Girder Over Bridge (HGOB) provides a lower profile allowing easier crossing for heavy transporters and tankers on line of communication routes. The bridge is transported on 1 DROPS pallet of a 14 tonne truck. A Royal Engineers Section and a crane is used to construct the bridge.
The stubs at the eastern end of the Dunn Memorial Bridge give a good cross section of girder bridge construction. A rolled steel girder is a girder that has been fabricated by rolling a blank cylinder of steel through a series of dies to create the desired shape. These create standardized I-beam and wide flange beam [7] shapes up to 100 feet in ...
Underslung (lower-beam) launching gantry used for Skyline guideway construction (2015). A launching gantry (also called bridge building crane, and bridge-building machine) is a special-purpose mobile gantry crane used in bridge construction, specifically segmental bridges that use precast box girder bridge segments or precast girders in highway and high-speed rail bridge construction projects.
In a plate girder bridge, the plate girders are typically I-beams made up from separate structural steel plates (rather than rolled as a single cross-section), which are welded or, in older bridges, bolted or riveted together to form the vertical web and horizontal flanges of the beam. In some cases, the plate girders may be formed in a Z-shape ...

The Alexis River Bridge, Labrador is a Callender-Hamilton type bridge. The Callender-Hamilton bridge is a modular portable pre-fabricated truss bridge.It is primarily designed for use as permanent civil bridging as well as for emergency bridge replacement and for construction by military engineering units.
Royal Engineers construct a Bailey bridge in Italy, September 1943. Wood planks are being laid over the stringers to construct the roadbed. 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.
The (non-modular) box girder bridge was a popular choice during the roadbuilding expansion of the 1960s, especially in the West, and many new bridge projects were in progress simultaneously. A serious blow to this use was a sequence of three serious disasters, when new bridges collapsed in 1970 ( West Gate Bridge and Cleddau Bridge ) and 1971 ...
