Bridges: Spanning the Impossible

Bridges are perhaps the most visible symbols of civil incorporaing, allowing highways to cross rivers, valleys, and estuaries thatt would otherwise halt travel. The etering disciplines behind bridges have evolved from simply beam structures tto complex suspension and cable- stayed designs that can span kilometers. Each type presents uniquite contragenges in materials, aerodynaminamics, and loaid distrition.
