Scheduled to start in early 2022, this seven-year project will see the construction of two shafts and a 3.4 km tunnel to carry electricity under the Dwyryd Estuary. The project has been developed to reduce the visual impact of National Grid’s overhead line across the estuary.
Hochtief UK’s Managing Director Lawrence Jackson said: “We are delighted to contribute with our long-standing expertise in tunnelling works to conserve and enhance the natural beauty and environmental heritage of Snowdonia”.
This is Hochtief’s second tunnelling project for National Grid. The Group is currently in joint venture for the delivery of the 32 km of tunnels for the supply of electricity in London.
