Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. [1] No moments are transferred throughout the support, hence their structural type is known as simply supported. The simplest beam bridge could be a log (see log bridge), a wood plank, or a stone slab (see clapper bridge) laid
A licensed engineer can help operators design a safe, appropriate timber bridge. Personnel from Virginia Tech have described in detail how to build a stringer bridge using standard bridge design procedures, for example, by placing timber stringers across the abutment, using a bent to support a trestle or timber frame. Their methods are quick ...

The term "covered bridges" is also used for structures in China such as Chengyang Bridge (1912) and Xijin Bridge (rebuilt 1718) which have large enclosed spaces, but for these it appears that space is not provided for commercial or residential use. The term "covered bridge" is sometimes used broadly to describe any "bridge-like structure" that ...
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 ...
Girder bridges have existed for millennia in a variety of forms depending on resources available. The oldest types of bridges are the beam, arch and swing bridges, and they are still built today. These types of bridges have been built by human beings since ancient times, with the initial design being much simpler than what we utilize today.
A trestle bridge is a bridge composed of a number of short spans supported by closely spaced frames. A trestle (sometimes tressel) is a rigid frame used as a support, historically a tripod used to support a stool or a pair of isosceles triangles joined at their apices by a plank or beam such as the support structure for a trestle table .
