Decoration:Building the Ultimate —— Suspension Bridge
In the world of bridges, the suspension is king. The suspension bridge is the only structure known to man that can span more than a mile. Defying gravity and makes light of difficult crossings. From the deck and the towers the magic of this bridge is how the load is distributed up to the cables and into the anchorage. This bridge must deal with many forces. It's own weight, the weather, and the weight of traffic.
