Geographically, the Thames Gateway is considered to run from Westferry in the west through Docklands to Southend-on-Sea and Sittingbourne in the east. Before 2003 most conspicuous development was situated west of Beckton although housing schemes at Chafford Hundred, Chatham and Greenhithe have been substantial, a large shopping centre at Bluewater and the international station under construction at Ebbsfleet in Kent indicate future focal points that will become important further east. Commercial investors remain hesitant until transport and social infrastructure is scheduled, funded and eventually developed at a pace that supports the oft-repeated political vision.
Comparisons may be drawn with developments east of Paris along the Marne valley.
