Welcome to the latest edition of In the Loop, your round up of local, national and worldwide bike riding 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). Modern materials such as steel and prestressed concrete allow us to build far larger arches than the ancient Romans did. As such, additional scaffolding or support systems are typically needed. 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. 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. But as with beams and trusses, even the mighty arch can't outrun physics forever. ![]()
