Modern arches typically span between 200 and 800 feet (61 and 244 meters), but West Virginia's New River Gorge Bridge measures an impressive 1,700 feet (518 meters). A scenic three arched stone bridge is the centerpiece of this 20 acre park. Modern materials such as steel and prestressed concrete allow us to build far larger arches than the ancient Romans did. If the deck is supported by a number of vertical columns rising from the arch, the bridge is known as an open-spandrel deck arch bridge. As such, additional scaffolding or support systems are typically needed. If the spandrel is solid, usually the case in a masonry or stone arch bridge, the bridge is called a closed-spandrel deck arch bridge. The tricky part, however is building the arch, as the two converging parts of the structure have no structural integrity until they meet in the middle. Arch bridge is one of the most popular types of bridges, which came into use over 3000 years ago and remained in height of popularity until industrial revolution and invention of advanced materials enabled architect to create other modern bridge designs. The ancient Romans built arch bridges and aqueducts that are still standing today. In fact, an arch made of stone doesn't even need mortar. It is the arch itself that gives its namesake bridge its strength. There are, for example, Roman, Baroque and Renaissance arches, all of which are architecturally different but structurally the same. While there's a fair amount of cosmetic variety in arch bridge construction, the basic structure doesn't change. Build a big enough arch, and tension will eventually overtake the support structure's natural strength. The greater the degree of curvature (the larger the semicircle of the arch), the greater the effects of tension on the underside of the bridge. Ulring focused on building analytic systems for large and mid-sized companies.
