The construction of a double of resort prospectus Sochi came to an end. The final work included the construction of a paired tunnel, which became the longest and most difficult among other tunnels of the main transport interchange of the resort. The understudy of the Prospekt is a new resort transport highway and is a unique road object combining overpasses and tunnels. The understudy includes forty artificial buildings: several dozen overpasses, transport interchanges and bridges, as well as a dozen tunnels. The construction of the understudy began in 2009, was carried out in a very difficult mountainous terrain and climate of the city, in tense urban conditions and transport overflow and overload. If we take into account the engineering and geological conditions, then according to them, the sabler of the resort prospect can be attributed to the most difficult transport projects of the world.
