An open-deck railway bridge in Leflore County, Mississippi. A railway bridge with its track and ties supported on load carrying elements of the superstructure (floor beams, stringers or girders) is called an open deck. When the track rests upon ballast, which is then carried by the superstructure of the bridge, it is called a ballasted deck.
Floor beams extend between the parallels of a chord and are used to support the stringers and decking. Floor beams may sit atop the chord below them, or they may be hung from the vertical posts. Floor beams generally have the greatest depth of any beam in the bridge. Floor beams are usually placed where two panels meet.
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
The term "girder" is typically used to refer to a steel beam. In a beam or girder bridge, the beams themselves are the primary support for the deck, and are responsible for transferring the load down to the foundation. Material type, shape, and weight all affect how much weight a beam can hold.

The orthotropic deck may be integral with or supported on a grid of deck framing members, such as transverse floor beams and longitudinal girders. All these various choices for the stiffening elements, e.g., ribs, floor beams and main girders, can be interchanged, resulting in a great variety of orthotropic panels.
The floor of the bridge consists of a number of 19-foot-wide (5.8 m) transoms that run across the bridge, with 10-foot-long (3.0 m) stringers running between them, and over the top of the transoms, forming a square. [3] Transoms rest on the lower chord of the panels, and clamps hold them together.
The approach road is a narrow gravel strip. The bridge itself is a 109.9 feet (33.5 m) long and 22.75 feet (6.93 m) wide, supported by abutments on either side of concrete on the upper level and stone laid in a random ashlar pattern below. Its main components are the two top and two bottom chords. [2] View of bridge from side
