Tunnel Sitiny in numbers
According to information from Slovak Administration of Roads tunnel is perforating only from one side – in a direction from Mlynská dolina. From the Polianky side will be prepared only a short sector, into which eventuates tunnel from the second side. Reason for this process is because of underground water in direction from Mlynská dolina, which can flow out alone by gravitation without help of withdrawing. Both of tunnel tubes are perforating quite synchronise. During whole building up of tunnel there will be realised monitoring of structure influence on environment, monitoring of earth consolidation-sinking above tunnel tubes during perforating and other necessary measurements.
