According to the DDC newsletter in the link below, the state-of-the-art landbridge will be built at the same time as the spectacular iconic tower and a commercial development similar to Gun Wharf Quays in Portsmouth.

This will accompany the building of an entire new ferry port in the Western Docks and a new marina in the harbour. Wellington Dock will become a freshwater reservoir nestling amongst residential towers and few will have any difficulty visualising it in the form shown below, somewhere to keep our cabin cruisers and superyachts at last, thank goodness.
Another DDC brochure shows the seafront lined with palm trees so French markets attending from St.Tropez should feel at home. Cable cars will criss-cross the gleaming new DTIZ development and bluebirds will dip and soar in the azure heavens above.
