The invention belongs to the technical field of building structure, which discloses a vertical steering steel-concrete combined arch bridge. The main implementation steps are as follows: steel box arc segments are assembled at the skewback vertically and concrete in the arch springing segment steel box is filled to form an upright semi-cross steel box arc bent frame; the steel box arc bent frame rotates around the lower end slowly to the span centre for folding to be coupled with an arch; the constructions of arc concrete beam and cross section steel box arc top concrete are finished to form integral steel-concrete combined arch structure; the constructions of bridge abutment, arch upright post and bridge deck are finished to form a whole bridge. The main arch structure is characterized in that the arch springing segment is an arch rib filled with concrete in the steel box, and the cross segment is a steel-concrete combined arch structure cast with concrete on the steel box top; ribbed stiffener boards of the steel box bottom and ventral shield besides the arch spring segment are all installed inside the steel box, and the stiffening plate on the top is installed on the steel box top by holing the ribbed stiffener boards and is also taken as a PBL shearing force bond of concrete combined with the steel box top board.
