This impressive engineering feat will consist of two tunnels, each will be designated for one direction of traffic, and they will have 11 meters in diameter and they will be separated by a distance of 60 m.
In this tunnel, the maximum speed limit will be 100 kilometers per hour, and it will be built at a altitude which will range from 3,750 and 4,000 meters above sea level.
