Suspension bridges might seem complicated, but for spanning long distances they can also be the most economical—they require less material per foot than would a simpler beam bridge. Because suspension bridges are relatively flexible, however, high winds and other forces can be a serious problem. read more

A beam bridge is the least strong type of bridge. Arch is in the middle because an arch has more support then a column, then suspension bridges are the strongest. ' +++ You cannot make that comparison, because each bridge is unique and designed for its location and predicted loads. read more
