    • A main tunnel: the main tunnel has length of 1,555 meters;
    • Escape tunnel: the same length 1,555 meters it has also. only tunnel longer than 1,500 meters have to have an escape passage alongside;
    • Shorter  tunnel and a road connecting the main and the 3rd tunnel: the shorter tunnel has a length of 980 meter and the road stretches 1,200 meters.
Benefits:
