The article deals with the creation of continuous metal and monolithic reinforced concrete bridge span structures, which are the most efficient. Efficiency is achieved by searching for opportunities to unify structures with the most successful options for providing them with the required load-bearing capacity with the lowest cost of building materials. If a certain coefficient of the length of the extreme relative to the average is introduced, there can be achieved the equality of the transverse moments of spans. Such performance of the structure will allow building the bridge span as if combined from three types of unified blocks, which would reduce the labor complexity and the cost of construction work.
