The invention discloses a highway-rail co-construction multi-span continuous steel truss girder bridge segment erection method, which is characterized in that a trestle, a temporary buttress, a crawler crane and a full-slewing crane assembly platform are sequentially arranged, two full-slewing cranes are respectively assembled and arranged on a large-mileage side and a small-mileage side, and a construction scheme of temporary buttress auxiliary half cantilever method installation is adopted. Four temporary buttresses are arranged between two adjacent main piers of an approach bridge section on one side in advance, one temporary buttress is arranged between the other main piers, then a crawler crane on a trestle bridge is used for installing four inter-section steel truss girders on the main piers and the four temporary buttresses, upper chords of the main piers and the four inter-section steel truss girders serve as a starting platform for suspended assembly, then two full-rotation girder erecting cranes are
