Description
Euston Station will be transformed as the London terminus for HS2. The project involves building a new station alongside the Network Rail station and creating over 600m of new tunnelled connections to the Euston London Underground (LU) station. The works include two new sets of escalators serving the Victoria line and Northern line Bank branch and three new lifts providing step-free access to all lines. Tunnel diameters range from 3.6m to 11.5m with most tunnels being constructed using sprayed concrete lining. In the tightest locations squareworks tunnels have been designed.
