The bridge construction is old as human civilization. Bridges are much important for infrastructure development of country. In design of any kind of structure, economy is the essential criteria. For the rail over bridges there are many types in superstructure. As per the criteria of RDSO they have given some standard design for some typical span of rail over bridge. But if the span differ from the given design span than we have to design bridge by considering RDSO design criteria. So it is important to decide the economic type amongst them. There are many types of bridge superstructures so there is two types considered among them. Which are bowstring Girder Bridge and steel concrete composite bridge. The decisions based on the obvious element of engineering that are safety, serviceability, and economy. Following this aspect, a design for different type of superstructures has been performed. After calculation the most economical has been selected.
