Provided is a method for construction of bridge balance type vertical turn. A bridge construction address of a hill is selected well, a main pier, an auxiliary pier and a slope are built at the bridge construction address, a rotating shaft is arranged at the middle of a bridge, so that weight spans of the bridge on the two sides of the rotating shaft are close or equal, the weight spans on the two sides of the shaft are as balanced as possible, so traction needed during turning of the bridge is minimum, and a traction device is not used or a minimum traction device is used to implement bridge vertical turn to be in position. The middle of the main pier is provided with a ground support, the bridge is vertically manufactured above the ground support, and the rotating shaft on the bridge is correspondingly positioned in a shaft support at the top of the main pier. After the bridge is manufactured, traction ropes are tied at the upper end and the lower end of the bridge respectively, the ground support is removed, the rotating shaft falls into the shaft support at the top of the main pier, and the traction ropes are pulled to rotate the bridge, so that the bridge floor is upwards until the bridge falls to the auxiliary pier.
