There are more than half a million bridges in the United States, and you rely on them every day to cross obstacles like streams, valleys, and railroad tracks. But do you know how they work? Or why some bridges are curved while others are straight? Engineers must consider many things — like the distance to be spanned and the types of materials available — before determining the size, shape, and overall look of a bridge.
Since ancient times, engineers have designed three major types of bridges to withstand all forces of nature.

The beam bridge…
consists of a horizontal beam supported at each end by piers. The weight of the beam pushes straight down on the piers. The farther apart its piers, the weaker the beam becomes. This is why beam bridges rarely span more than 250 feet. Source: PBS
Calton Foundations has built many private bridges for land preserves, cow pastures, homes and agricultural projects. Please call us today for your bridge project.
