The bridge can be constructed by hand but the components are extremely heavy. Like the Medium Girder Over Bridge it is used to reinforce current bridges to allow heavier traffic also like the Medium Girder Over Bridge it can also be used as a bridge on its own but it does require extensive foundations.

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.

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 ...
A Vierendeel bridge is a bridge employing a Vierendeel truss, named after Arthur Vierendeel, a Belgian engineer who proposed this new bridge girder-type without diagonals in 1896. [ 1 ] Such trusses are made up of rectangular rather than triangular frames, as are common in bridges using pin–joints .
Attempts have been made to increase the safety of bridges with pin and hanger assemblies by adding some form of redundancy to the assembly. Retrofits that add redundancy to pin and hanger assemblies include adding a "catcher's mitt"—a short steel beam attached to the bottom of the cantilevered girder that extends out beneath the suspended girder to "catch" the suspended girder should ...
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 ...
