Generally, because concrete has massive compression strength and steel has incredible tensile strength. Combined, they make amazingly strong structures.
Steel reinforced concrete is concrete with rods of steel running through it.
Favorite materials for bridges include steel, aluminum, titanium, wood, stone, and reinforced concrete.
Concrete can be reiforced by using steel; steel can not be reinforced
Reinforced concrete is just normal concrete with steel reinforement placed inside.
Arch bridges are made from arches. Arches are typically made from brick, reinforced concrete, stone or steel. Wooden arches are sometimes used for ornamental bridges, such as decorative footbridges in gardens.
The steel rods are there to strengthen the concrete - making it reinforced concrete.

A common characteristic of reinforced concrete bridges is that they feature a combination of concrete and steel reinforcement to provide added strength and durability. The steel reinforcement helps to enhance the tensile strength of the concrete, allowing the bridge to better withstand forces like tension and bending.

I think you are talking about embedding steel rods (rebars) in concrete, right? This would make the concrete much stronger. It is called reinforced concrete, and you can make all sorts of structures with it, something that you can't do with ordinary concrete. Though, I am not even sure anyone is using non-reinforced concrete nowadays.
Concrete is usually reinforced by adding steel. The cost of reinforcing concrete depends with the given area under which the steel is placed to reinforce it.
Reinforced concrete has steel bars embedded in it. It is also called re-barred concrete.
Reinforced concrete is concrete reinforced with steel bars because although concrete is very strong in compression (depending on its components) it is very weak in tension and the steel bars make up for the required tensile strength.
