THREE-LEVEL ROAD JUNCTION OF CROSSING EXPRESS URBAN HIGHWAYS AND CONTINUOUS TRAFFIC URBAN HIGHWAYS

摘要

The three-level road junctions find application in construction in the crossing of express urban highways with continuous traffic urban highways. They are used in built-up streets where it is possible to ensure a distance of 30 to 60 m between the outer borders of the two roadways. Crossing of the highways is carried out at three levels (1, 2, 3), direct passage being ensured for the four main directions û AC, CA, BD and DB, while the car traffic in the rest eight directions is controlled by traffic lights, the dividing line along the main directions being solid.
