Metro Tunnel

Project timeline

Metro Tunnel is currently in the planning and design phase. Projects of the scale and complexity of Metro Tunnel require long lead times to develop and construct.

Engagement is ongoing to raise awareness of the project and build our understanding of the needs and wants of residents, businesses, landowners, councils and other stakeholders. Feedback input informs the design, development and delivery of Metro Tunnel.

Construction will commence in 2017 with the project anticipated to be completed and operational in 2026.
