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
Using fallen trees, stringer bridges can be built. Wood laminated by stress, glued, dowels, or nails lumber are good for panel bridges. New lumber and wood scavenged from buildings and railroad ties can be used to build stringer bridges. [3] A licensed engineer can help operators design a safe, appropriate timber bridge.

Floor beams generally have the greatest depth of any beam in the bridge. Floor beams are usually placed where two panels meet. If they are placed somewhere mid-panel, the chord must be reinforced to resist bending, buckling, and shear stress. [18] Stringers are beams set on top of the floor beams, parallel to the chords.

The bridge is of beam-type construction, approximately 3.1 miles (5.0 km) in length, and travels roughly east–west. The eastbound (carrying I-295 South traffic) and westbound (carrying I-295 North traffic) lanes are built on separate bridge structures. Average daily traffic in 1996 was estimated at 78,000 vehicles.
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 bridge is a single-span steel beam stringer bridge, resting on I-beam pile abutments with concrete wings. The bridge is 26 feet (7.9 m) long. Built in 1917, it was one of the first bridges built in the county by county employees, rather than by hired bridge companies, and predates the formation of state highway department by two years. [2]
