Dormay Street

Site information

This site is being used to connect the existing local combined sewer overflow (CSO) to the main tunnel. It is also used to drive a long connection tunnel southwards to King George’s Park and northwards to Carnwath Road Riverside, to connect the CSOs at Dormay Street and King George’s Park to the main tunnel. This connection tunnel is known as the Frogmore connection tunnel.

Dormay Street

Charlotte, our Tunnel Boring Machine (TBM), began her journey towards King George's Park in March 2019. She arrive to site in late October.

You can read about the recent break through here.

Charlotte has been driven back over to Dormay Street where she will complete the rest of the Frogmore Connection Tunnel towards Carnwath Road.
