Cable-stayed bridge Cable-stayed bridge A cable-stayed bridge has one or more "towers" (or "pylons"), from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the
Cable barrier several types of highway barrier did not find an appreciable difference in fatal and severe injuries between cable barrier and W-beam barrier. Both were significantly more hazardous than concrete barrier, however were less hazardous than having no barrier at all. There are two types of cable barrier systems in use today, low-tension and high-tension. Each system has its advantages and disadvantages, but in general, a high-tension system has a higher initial cost with lower long-term maintenance costs and concerns. During the expansion of cable barrier use throughout the 1980s and 1990s, the low-tension system was specified almost exclusively. This system
