Beam Bridge 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.

How do you structure a bridge?

For designing safe bridge structures, the engineering design process includes the following steps: 1) developing a complete understanding of the problem, 2) determining potential bridge loads, 3) combining these loads to determine the highest potential load, and 4) computing mathematical relationships to determine the …
