The TBM will excavate the National Grid tunnel that will carry 400kV electricity cables to replace the existing 3km overhead line across the Dwyryd Estuary.
The VIP project in Eryri National Park aims to reduce the visual impact of the overhead electricity line across the Dwyryd Estuary from Minffordd to Llandecwyn. It includes constructing two new tunnel head houses, which will provide access to the tunnel, along with a sealing end compound to connect the underground cables with the remaining overhead line.
