Suspension bridges tend to be the most expensive to build. A suspension bridge suspends the roadway from huge main cables, which extend from one end of the bridge to the other. These cables rest on top of high towers and have to be securely anchored into the bank at either end of the bridge.
.
Considering this, what materials are typically used to build suspension bridges?
On some suspension bridges, the steel wires forming the cables have been galvanized (coated with zinc). The towers of most suspension bridges are made of steel, although a few have been built of steel-reinforced concrete.
Additionally, how is a suspension bridge built to withstand forces? Suspension bridges get their name from the fact that the roadway is suspended by cables from two tall towers. Most of the weight is supported by the two towers. They in turn pass the compression forces from the cables directly into the ground. Suspension bridges also have smaller cables called suspenders.
One may also ask, how are cables placed on a suspension bridge?
The main forces in a suspension bridge are tension in the cables and compression in the towers. The deck, which is usually a truss or a box girder, is connected to the suspension cables by vertical suspender cables or rods, called hangers, which are also in tension.
What are the strengths of a suspension bridge?
Suspension bridges are flexible, which is an advantage until conditions become severe. Instability in extremely turbulent conditions or during strong earthquakes may require temporary closure. In 1940, high winds caused the Tacoma Narrows bridge, near Seattle, Washington, to collapse.

Why do suspension bridges fail?
The top reason bridges fail is a mix of factors that, if they happened individually, would not cause a bridge to collapse. However, when they take place all at once, they result in devastating consequences. However, when they hit a bridge that's structurally too rigid to withstand them, it leads to failure.How old is the I 74 bridge?
