Bridges are almost invariably built from steel due to its high structural strength, flexibility and relatively low cost.
The price of steel will vary depending upon what structural shape is being bought. The price could range from 30 to 60 cents a pound depending upon the shape.
The high-rise building was made feasible by two things- the low cost availability of structural steel framing, and the invention of the elevator. Without elevators, no one is going to want to live or work on the 35th floor of a building.

There are many different types of steel. It would depend on the specifications of the steel.
The cost to make a commercial steel building depends on many factors, such as the square footage, the price of materials, the cost of the concrete foundations, the steel building labor costs, etc.
That depends upon so many factors. Are you buying plate, sheet, structural steel? Most steel (in the US) is sold by the hundred weight, cwt. You can also buy it by the foot, square foot, pound, each, etc. Stainless steel runs about 5 times mild hot rolled steel. Cold finished, turned ground and polished bar stock also costs more, typically, than mild steel. Also, steel prices have fallen rapidly in recent months, and there is variation in price from one place to another, of course. If you want to keep your cost low you might request a commercial quality grade. If your application is more specialized, such as firebox steel for stoves, or abrasion resistant steel like T1 (A514), you can expect to pay more. A typical mild steel bar might cost around $100 per hundred pounds. You can often negotiate a better price by buying in quantity.
carbon fiber costs more than steel
