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
Some bridges are measured from the beginning of the entrance ramp to the end of the exit ramp. Some are measured from shoreline to shoreline. Yet others use the length of the total construction involved in building the bridge. Since there is no standard, no ranking of a bridge should be assumed because of its position in the list.

Box girder bridges, made from steel, concrete, or both, are also beam bridges. Beam bridge spans rarely exceed 250 feet (76 m) long, as the flexural stresses increase proportionally to the square of the length (and deflection increases proportionally to the 4th power of the length). [28]
The Braga Bridge is a continuous truss bridge. It was the fourth longest span of this type when it was completed in 1966. This list of continuous bridge spans ranks the world's continuous truss bridges in two listings: The first is ranked by the length of main span (the longest length of unsupported roadway) and the second by the total length of continuous truss spans.

The Dhola-Sadiya Bridge, officially known as Bhupen Hazarika Bridge, is a beam bridge in India, connecting the northeast states of Assam and Arunachal Pradesh. [1] The bridge spans the Lohit River, a major tributary of the Brahmaputra, connecting the village of Dhola in the south to the village of Sadiya to the north, both in Tinsukia district of Assam, and providing convenient access to ...
