Bridges with steel material can enter into any of each three categories described on Section 3.2.2. Depending on the type of steel to be used, yielding allowable stress of the structural steel can vary between 36 ksi (249 MPa) and 70 ksi (483 MPa).
Reinforced concrete bridges are found to be economical for spans exceeding 12 m. Prestressed concrete bridges have been constructed for spans up to 60 m. Arched concrete bridges have been built for still greater spans. Since steel possesses a high working stress compared to other materials, steel bridges work out to be economical for large spans.(plate) Chapter 5 RC Box culverts Final - Wyoming Department (steel) greater than 10'-0". This type of culvert uses moment resisting steel at the wall-to-slab joints which reduce the bending moment in the slabs. Reinforcing steel is continuous between the slabs and walls.

The steel in the bridge is held together by tens of thousands of rivets, each was which was placed manually.
Reinforced concrete bridge approaches are built at the ends of a bridge with a minimum length of 20 ft. They are generally reinforced with two mats of steel and are built to a specified thickness. The purpose of a bridge approach is to eliminate settlement of the pavement at the bridge ends.

FoundationDeckingSupplemental ComponentsThe foundation also called pile serves as the legs or main support of the entire bridge structure. The pile receives the entirety of the load on the bridge structure anddistributes this amount of force to the ground below. Modern bridge construction makes use of in-site piling. In this kind of process, holes are bored deep into the ground where reinforced steel is installed,and concrete is poured into the perforations. These in-site piles are grouped See more on matmatch12 Types of Loads Considered for Design of Bridge Structures(steel) Tracked vehicle (steel bridge) 10% for all spans Wheeled vehicle (steel bridge) 25% up to 23 m If the length exceeds in any of the above limits, the impact factor should be considered from the graph given by IRC which is shown below.
