Lets' look at this from a simplistic point of view.
The predominant factors when dealing with a bridge is strength and weight. The strength of the bridge is how much load it can handle. The weight is how much the bridge weighs before loads (such as cars) are applied. The weight of the construction material must be included when considering the total strength of the bridge. For instance, if a bridges strength is 110 pounds, and the weight of material is 100 pounds, then you can only put 10 pounds on the bridge before failure.
Bridges can be made from any material. Wood is commonly used on hiking trails, Composite (Plastics) have been used on some small bridges. However, the two most popular are Steel, and reinforced concrete (Reinforced Concrete has steel rods inside the concrete to increase the strength).
The reason for this is because of the incredible strength of the steel or concrete per pound of material. This allows for a very strong structure that does not generate a lot of weight. This means that the load carrying capacity of the bridge is maximized.
Furthermore, the structural design of a bridge allows for load shifting. This explains the grid pattern above, or below, some bridges, the big arch under some concrete bridges, or the characteristic look of suspension bridges.

What element that use to make bridges?
steel
What is used to make steel bridges?
iron ore
What are steel bridges made of?
steel bridges are made out of steel OBVIOUSLY !!!
How did the bessemer process make suspentioins bridges possible?
The process removed the impurities from the iron creating steel. Therefore steel could be used to make bridges, buildings, and other things.
What has the author John W Fisher written?
John W. Fisher has written: 'Fatigueand fracture in steel bridges' -- subject(s): Bridges, Iron and steel, Fatigue, Fracture, Iron and steel Bridges, Steel, Structural, Structural Steel
What a metal use to build bridges?
Bridges are almost invariably built from steel due to its high structural strength, flexibility and relatively low cost.
Do steel investment foundries make use of steel scrap?
Steel investment foundries make use of steel scrap
What are uses of recycled steel?
Recycled steel is just as good as fresh steel made from iron ore from the earth. So recycled steel can be used to make anything. Vehicles, bridges, stainless steel, everything!
Both steel and chalk are solids What properties of steel make it more useful than chalk for building bridges?
the steel has stronger force between its atoms compared to chalk
What new uses for steel were developed at this time?
Some uses for steel when it was first developed was the use of it for railroads. Also, it was used for buildings, structures, and bridges.
