The present invention relates to the technical field of bridge erection, and provides a method for erecting a continuous steel truss bridge. The method for erecting a continuous steel truss bridge comprises: constructing a main substructure and a rotation structure, and mounting a pier-top steel girder on a pier-side support by means of a tower crane; symmetrically hoisting a preset number of steel girder sections along two sides of the pier-top steel girder by means of the tower crane, and hoisting in place a temporary erection tower on the pier-top steel girder; hoisting in place a temporary support tower at the top of the temporary erection tower by means of the tower crane, and hoisting in place two bridge deck cranes by means of the tower crane; symmetrically and synchronously hoisting the remaining steel girder sections by means of the two bridge deck cranes, and at the same time, hanging temporary cables at corresponding positions and tensioning same; and removing unnecessary construction loads on a br
