Eucumbene Snowy
The Eucumbene-Snowy is a tunnel of the Snowy Mountains System with a length of 23.5 kilometers and a maximum diameter of 6.35 meters, in which water is passed through. It is the longest tunnel in the system, one of the main tunnels. The entire tunnel system in the Australian Snowy Mountains in New South Wales is 145 kilometers.
The water from the Snowy River, which is fed into the Island Bend Pondage water reservoir , leads the tunnel to Lake Eucumbene , and if it is needed for Island Bend , it can flow there through the Snowy-Geehi Tunnel .
The construction time for the tunnel was four years, since the Snowy Mountains consist mostly of granite , the tunnel system had to be built with drilling tools. In the tunnel there was a steel work scaffold with three work platforms. For each platform there was a hydraulic drive on rails and drilling rigs and other equipment were used on the platforms to drive the tunnel. Steel tie rods of different lengths were built into the rock roof of the tunnel to help prevent it from collapsing.
A world record is said to have been set in tunneling in the Snowy Mountains system in 1963, when 165 meters in the Snowy Geehi tunnel were built in a period of one week.
