How many construction sites will be needed to create the Thames Tunnel?
To construct the Thames Tunnel we currently expect to need up to six main shaft sites (including one at Beckton Sewage Treatment Works), which will be access points for the machinery required to build the tunnel. We also anticipate needing up to five smaller intermediate sites. In addition we need to connect the most polluting Combined Sewer Overflows (CSOs) to the Thames Tunnel. These are all at existing, fixed locations along the River Thames.
