The invention relates to an overpass, in particular to a double-layer-structure overpass at a crossroad. The overpass comprises twelve lanes. Four right-turning lanes and two through lanes are arranged on the first-layer ground, and four left-turning lanes and the other two through lanes are arranged on the second-layer overpass floor. The double-layer-structure overpass is characterized in that as four corners (or three corners, or five corners) are used, all the left-turning lanes extend from the first-layer ground to the second-layer overpass floor and then extend from the second-layer overpass floor to the first-layer ground to achieve left turning. Meanwhile, the other two through lanes extend from the first-layer ground to the second-layer overpass floor and then extend from the second-layer overpass floor to the first-layer ground to achieve through traveling. In order to achieve passing of coming and going pedestrians, four pedestrian paths are arranged on the first-floor ground of the overpass, and meanwhile road traffic signal lamps shared by the coming and going pesticides and coming and going vehicles are arranged. By means of the overpass, overpass falling accidents can be avoided.
