Q. Write a short note on Economic Span of a Bridge?

The span for which the total cost of bridge will be minimum is known as the economic span.

The ratio of Cost of super structure and Cost of Sub structure = 1

Economical Span = √P / a  , 

Where -    a = p / l2 ,  p = Cost of pier ( Super structure ) ,   l = Span, 

                 P = Cost of Pier ( Sub Structure ) ,     a = Constant of variation.
