A crossroad completely-unblocked cross-type combined bridge with a right-turn bridge being at the outer side of the utility model is a combined structure which is formed by combining four independent bifurcated arch bridges and can make several bridges at the crossroad be unblocked. Each bifurcated arch bridge is provided with a straight-running arch bridge and a left-turn bridge; the left-turn bridge is located at the left side of the straight-running arch bridge; the left-turn bridge is bifurcated from the straight-running arch bridge at the left-turn side so as to form a halberd-shaped bifurcated bridge; four bifurcated arch bridges form four halberd-shaped bifurcated bridges bifurcated in a same direction; two halberd-shaped bifurcated bridges bifurcated in a same direction form a grouping bridge; two groups of straight bridge one-way segments of two grouping bridges form a stereoscopic cross-type structure. Four right-turn bridges are at outer sides of four left-turn bridges. The advantages are that wide ground is used as a merging driveway section, which is not easy to cause traffic jam; no superfluous bypassing is required for left turning and right turning; roads are returned to pedestrians below the combined bridge; and a two-way six-driveway small crossroad is allowed to be completely unblocked.
