The works took more than two years to complete and included more than 7,700 m3 of concrete and nearly 8,000 t of reinforced steel.
Work is now underway to connect the new entrance with the Metro Tunnel’s twin 9km tunnels.
All four of the project’s tunnel boring machines are currently digging underground, with approximately three quarters of tunnelling now complete.
