Cable-stayed bridges are of a unique design that are the ideal structures for crossings in which a regular cantilever bridge is not long enough and a suspension bridge is not feasible for one reason or another. A cable-stayed bridge is a great alternative to a suspension bridge at a crossing where the soil on either side is not strong enough to support the main cables, or the cost of the excessive amount of cables to get across the gap would far outweigh that of the cable-stayed. Crossings that are too large would mean that a cantilever bridge would become heavy to the point that the roadway would be compromised and the cost of materials would be too great. Cable-stayed bridges also offer engineers and architects a chance to create a bridge that is not only functional, but aesthetically pleasing. This episode will include interviews with engineers and architects to find out what goes into making a bridge like this a reality and this pro’s and cons to this type of construction.
