If we can adapt the traditional truss design to accommodate new materials and utilize comprehensive supports, then many of the negatives of this bridge design can be limited. Building a truss bridge can be costly, and its upkeep requires time and money. The key benefit of using a truss bridge to span a distance is that they are relatively lightweight, but can still be reinforced to provide strength. One of the primary reasons that truss bridges have been the preferred structures over other types is their versatility to be constructed in places where construction could be difficult, such as locations needing long span of areas like deep trenches. Engineers can install this type of bridge almost anywhere in the world today because of the efficiency of its design. This makes the truss bridge both versatile and economical to build. Bridges built over a lengthy span may have several deflection problems that must be rectified during the construction phase. A cable stayed bridge is a design which has the weight of the bridge deck supported by several cables that run to a single tower or several towers, depending upon the size of the bridge. Each part plays an integral role in the integrity and safety of the bridge, requiring close monitoring.
