Costing nearly £5 billion, London’s super sewer - officially named the Thames Tideway Tunnel - has opened four of its 21 sites, with the full system due to open in 2025.
The tunnel is part of an effort to reduce pollution and clean the city’s iconic river. Speaking with Times Radio, Tideway chief executive Andy Mitchell said: “We are starting to have an impact, we have got a long way to go but the cleaning up of the tidal Thames has definitely started.”
