Work update

The team has carried out footway reinstatement works around the Kirtling Street and Brooks Court sites. All traffic diversions around Cringle Street and Kirtling Street have now been lifted and traffic has reverted to two-way.

The team has also completed asphalting the section of the Kirtling Street road that is located within the Tideway compound. This section of road will, however, remain closed to public traffic until the completion of Tideway's works in 2025.

The team is continuing with reinstatement works across the site and is starting to hand-back various parcels of the land to the relevant landowners as the project reaches its conclusion.
