Work update

The team is carrying out footway reinstatement works around the site. There is a one-way traffic system in place, with no turning into Cringle Street from Nine Elms Lane and traffic for WRWA and Riverlight diverted via Pump House Lane. Vehicles exiting the Riverlight Estate can turn left into Cringle Street and then onto Nine Elms Lane.

From 8 April, we will start asphalting the section of the Kirtling Street road that is located within the Tideway compound. We will start at the junction of Kirtling Street and Cringle Street and make our way through the Tideway site to complete the L shape of the road up to the Riverlight area. The works are expected to take 2-3 weeks to complete, weather dependent.

On completion we intend to remove the last of the traffic management in Cringle Street at the junction with Nine Elms Lane. Cringle Street will then revert to two-way traffic.

Our working hours

Standard working hours are:

Monday to Saturday: 7am to 8am - quiet works and setting up
