PURPOSE: A connecting structure for an interchange is provided to reduce traffic congestion in the interchange by turning left or right and moving forward in the narrow space, and to go into the interchange variously according to the topography by changing the direction conveniently. CONSTITUTION: An interchange for three streets is composed of a first road(10) and a second road(20). A branch road(30) is connected to the first road and the second road to turn the vehicles to the right from the first road and the second road. A left-turn road(40) is constructed and branched from the first road or the second road to turn the vehicles to the left from the first road or the second road by turning over 360 angular degrees. The vehicle is turned to the right from the first road or the second road by the triangular branch road. The left-turn road is branched from the outside of the travel line of the first road, and jointed to the second road by turning 360 angular degrees.
