A beam or "girder" bridge is the simplest and most inexpensive kind of bridge. According to Craig Finley of Finley/McNary Engineering, "they're basically the vanillas of the bridge world."
In its most basic form, a beam bridge consists of a horizontal beam that is supported at each end by piers. The weight of the beam pushes straight down on the piers.
The beam itself must be strong so that it doesn't bend under its own weight and the added weight of crossing traffic. When a load pushes down on the beam, the beam's top edge is pushed together (compression) while the bottom edge is stretched (tension).
The farther apart its supports, the weaker a beam bridge gets. As a result, beam bridges rarely span more than 250 feet. This doesn't mean beam bridges aren't used to cross great distances-it only means that they must be daisy-chained together, creating what's known in the bridge world as a "continuous span."

What is the difference between beam bridge and an arch bridge?
Arch bridge: the span beam of bridge is the shape of an arch & the load is diverted in compressive method. Beam bridge: the shape of beam span is of simply supported or continuous. here the load is diverted through bending compression method.
