The invention provides a cable terminal and span bridge integrated tower. The cable terminal and span bridge integrated tower is composed of two terminal units and a bridge unit, and the terminal units are located on the two sides of the bridge unit. The terminal units each include a tower body, a ground electrode cross arm, an upper layer wire cross arm, a middle layer wire cross arm, a lower layer cross arm, an auxiliary cross arm, a cable terminal shaped like a Chinese character ''bu'' , and a cable. An overhead line is connected to the terminal unit on one side and converts into a cable byusing the corresponding cable terminal shaped like a Chinese character ''bu''. The cable is arranged downward from the cable terminal shaped like a Chinese character ''bu'' of the terminal unit on one side along the tower body at the side, facing the bridge unit, of the terminal unit, and enters the bridge unit, and enters the terminal units on the other side along cable bracket in the bridge unit. The force-bearing characteristics of a tower body structure is used for erecting a span bridge, so that the crossing of undercrossing highway lines is realized, obstacles are effectively avoided, the construction cost, construction difficulty and construction time are reduced, and the overall beauty is not affected.
