Modern Bridge Building
Modern technology is advancing faster than we care to think. Our engineering marvels of the past are quickly becoming obsolete. Many bridges are built using classic designs which can be greatly improved with new technology. Modern technology allows bridges to be built from state of the art materials with superior strength and versatility (Wilson I). The arch is one of the older forms of bridge used in many Roman structures. It is like an inverted suspension bridge, with all the tensions replaced by compressions, and vice versa. The other great difference is in the stability of the system. You can drive heavy weight across an arch and cause it to flex, and it will always return to its original position, after movement. The girder bridge is made up of two or more large beams that can stretch across the length of the obstacle that it is built to overcome. Many cantilevers that pivot as the load on the bridge shifts are used to even out the stress on th
