Purpose of this paper is primarily to justify increasing use of prefabricated beam concrete bridges today from aspect of economy and racionality, their increasing growth of competitiveness on the market and probably suppressing tradicional way of building in the future. With numerous examples we will go through all the methods and technologies of building these bridges. This paper will be based on application of prefabricated elements which are same length as in exploatation. It should be noted that prefabricated elements can be shorter than elements in exploatation, which results in some other methods of building.
