Some more detail on EES processing here:
https://www.bbc.co.uk/news/articles/ckmm866p23mo. In addition to coach traffic being processed at the "Western Docks" (including going through border controls and being sealed), car traffic will also move "there" by 2027 - providing the Granville is filled in. Where border controls will eventually be for car traffic, isn't stated.
I can see the reasoning for coach traffic if it were a temporary measure pending reclamation and/or infrastructure at the Eastern Docks, but the car business surprises me. It seems to me that saying 'you will first visit the Western Docks' is almost like saying 'you will use the A20'. Also, to get into the site you have to cross (ie. stop) inbound traffic - and again leaving it, which was one of the fears after the referendum concerning post-Brexit processing at Western Docks of 100% of freight traffic.
