Bridge Inspections For A Safer Infrastructure
Amazing Cable Stayed BridgesApril 12th, 2016 Author: Doug Thaler
Cable Stayed Bridges although similiar in appearance to a suspension bridge are actually quite different. Cablestay bridges are faster to build, more cost effective and best for bridges from 500 to 3000 feet. A cable-stayed bridge has cables that run directly from the towers to the road. The weight of the road deck of a cable-stayed bridge is balanced on each side of its towers evenly and does not need anchors or anchor blocks like a suspension bridge. Here are some amazing cable stayed bridges.
