Second tunnel excavated for Snowy 2.0


The Snowy 2.0 pumped-hydro mega project has achieved another important construction milestone, with a second tunnel excavation completed at Lobs Hole in the Snowy Mountains. The 2.93-kilometre emergency, cable and ventilation tunnel (ECVT) has been excavated and fully lined with 13,140 locally-manufactured concrete segments by tunnel boring machine (TBM) Kirsten. This achievement follows the excavation of the adjacent main access tunnel (MAT), which was completed in October 2022.
