What type of bridge is the strongest and why?
An arch bridge is stronger than a beam bridge, simply because the beam has a weak point in the center where there is no vertical support while arches press the weight outward toward the support.
What makes a beam bridge strong?
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.
