Tideway Project Update: TBM Ursula Reached Her Final Destination

Tunnel Boring Machine (TBM) Ursula broke into the central section of the Tideway project in London, finishing her drive from Battersea to Bermondsey shaft in December 2020.

Tideway project geologist Tim Newman added: “Completing the longest single drive on the Tideway project is a wonderful milestone, and our teams have made great progress through a challenging year.”

More than a million tons of spoil was transported by the barges over the Thames river while digging up the sewer. Meanwhile, 4,227 concrete rings were installed by TBM Ursula to line this section of the Thames Tideway Tunnel.

The Ferrovial and Laing O’Rourke JV has delivered more than 19km of the project. Shortly TBM Selina will be put into operation to complete the last 5.5km part of the super sewer.

“With around four-fifths of the tunneling now complete, everyone on Tideway is focused on getting this job done safely and delivering a cleaner Thames for the city.”
