(57) The present invention relates to a prestressed girder for a bridge, and a manufacturing method therefor, and symmetrically provides tendons to be connected from two anchoring parts at one end of a concrete part to one anchoring part on the other end of the concrete part, and thus introduces tensile force from one anchoring part. Therefore, the present invention has the effects of introducing an accurate amount of prestressing force through intended tensile force by allowing uniform tensile force to be introduced to respective strands constituting each tendon, and enabling the transverse curvature of the girder to be prevented by simultaneously introducing tensile force to the tendons symmetrically arranged with respect to a transverse central line.
