The A2203 is an alternative access road to the Blackwall Tunnel en route to the Millennium Dome.
The road starts from the traffic-signalled junction with the A206 Woolwich Road at shabby East Greenwich. The concrete block of the former Greenwich District Hospital is behind us and awaits redevelopment. Blackwall Lane forms the whole length of the A2203 and we soon pass under the flyover for the Blackwall Tunnel Southern Approach. This junction is now full access but previously only northbound traffic could access the A102 Blackwall Tunnel Approach Road and only southbound traffic from Blackwall Tunnel could exit on to Blackwall Lane. Prior to that, the A102 ran along Tunnel Avenue just to the west - and the A2203 ended on it.
The A2203 has been lengthened slightly from its 1922 route and now terminates on a roundabout on the far side of the A102 with the former A2052 and Millennium Way which leads to the Dome, North Greenwich Underground and Bus Station. Nearby is a new ecological nature park and environmentally friendly flats, Sainsbury's and Multiplex Cinema.
