The invention relates to a cross-shaped dual-direction cable-stayed bridge structure. The cross-shaped dual-direction cable-stayed bridge structure comprises a longitudinal beam body and a transversebeam body, wherein the longitudinal beam body and the transverse beam body are mutually perpendicular, a cable tower is vertically arranged on the intersection of the longitudinal beam body and the transverse beam body, longitudinal stay cables are arranged between the cable tower and the longitudinal beam body, and transverse stay cables are arranged between the cable tower and the transverse beam body. According to the cross-shaped dual-direction cable-stayed bridge structure, vertical transverse cable holes are formed in the position, in a certain distance from longitudinal cable holes of an original cable-stayed bridge, on the basis of retaining the original ordinary linear-shaped single-direction cable-stayed bridge, additive stay cables penetrate through the transverse cable holes, the lower parts of the cables are anchored to an additionally arranged beam body, so that the use function of the cable-stayed bridge can be effectively improved, dual-direction transportation is achieved, the total space occupation is less, the transportation efficiency is distinctly improved, the appearance looks good, construction technology is mature, and the cross-shaped dual-direction cable-stayed bridge structure is simple and easy to operate, and is an extremely spreading-valuable bridge structure.
