Side-spar cable-stayed bridge the direction of the roadbed. Side-spar cable-stayed bridge A side-spar cable-stayed bridge may be an otherwise conventional cable-stayed bridge but its cable support does "not span the roadway", rather being cantilevered from one side. The Esplanade Riel illustrated is located in Winnipeg, Manitoba, Canada. This bridge is intended for pedestrian use only and has a restaurant in its base. In the example below the cable paths are aligned with the bridge centerline, so that structurally it differs only in the transfer of stresses through the tower to the foundation. The side-spar principle is not limited to a straight bridge, however.
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
