Impact on the Post Office tunnel from SCL Tunnelling at Liverpool Street

Under the umbrella of projects that make up Crossrail, C510 is the construction of tunnels which will form the new Liverpool St and Whitechapel stations. These works include the mining of platform tunnels, access passages, ventilation ducts, cross passages and escalator passages which will go on to make up the new station infrastructure.

At Liverpool St, C510 has constructed a temporary access shaft in the centre of Finsbury Circus gardens, situated west of the Liverpool St National Railway Station. To date, this is where all surface level access to the developing tunnel network has been gained. Due to the complex nature of the tunnel infrastructure, SCL was chosen as the method of tunnel lining, due to the flexibility it enables.
