A bridge ballastless track structure is applied to a special long and large bridge and capable of greatly reducing the action force of a girder track, and keeping the unity of a all track structure. A reinforced concrete track bed board (40) has an integral structure formed by continuous cast in place along the length of the bridge, a reinforced concrete base (30) and the reinforced concrete track bed board (40) are fixedly connected by a jointed element, and a precast sleeper element (41) is embedded in the reinforced concrete track bed board (40); a sliding layer platform (20) is arranged at the top of a bridge body (10), and a sliding layer (21) is paved between the bottom surface of the reinforced concrete base (30) and the top surface of the sliding layer platform (20); at the fixing end of the bridge body (10), the reinforced concrete base (30) is fixedly connected with the bridge body (10) by a connecting structure; and at two sides of cross bridge directions of the reinforced concrete base (30) and th
