PROBLEM TO BE SOLVED: To provide the connecting structure of a box culvert, in which the formation of an air reservoir between a cut off material and a concrete structure can be prevented simply and efficiently, and its construction method. SOLUTION: In the connecting structures of the concrete structures in which the cut off material 10 with a flexible section and a pair of fastening sections 12 continuously connected to the flexible section is arranged between a pair of the concrete structures 15, the flexible section is arranged along a joint for a pair of the concrete structures 15, and a pair of the fastening sections 12 are buried in the concrete structures 15 opposed while holding the joint respectively. In the connecting structures, the cut off material 10 is disposed while forming an inclination (θ) of 2 or more degrees from the central sections 19a of floor slabs 19 for the concrete structures to side walls 20 on both sides on the cavity cross sections of the concrete structures 15.
