This left the motorway in two sections, with the gap running via the A20 – this was referred to locally as "The Missing Link". The level of traffic was not considered necessary to complete the route. Most of the traffic for the Channel ports was using the A2/M2 route. When the Channel Tunnel was ready for construction, it was decided to complete the M20 between junctions 8 and 9 and this opened in 1991. Concurrent to this was the extension to Dover as part of the A20 which opened in 1993. A new junction was also constructed (11A) for the Channel Tunnel.
