Bear with me.
There are far too many shops in Dover between the Market Square and The Sportsman Pub, a distance of near enough a mile, and most of it on a road originally developed to take all of the traffic out of the port in event of the Folkestone Road being blocked, hence being two lane.
Much of it is low quality ribbon development, being the result of perfectly nice Victorian terraces having their frontages often changed into single story shop extensions leading directly onto the pavement.
Wander down the road as I have, look up above the ground floor and there's some really nice buildings. At street level they are crap.
It's not a particularly nice road to live in, shop in or even drive along.
As well as the Folkestone Road we now have the A20/M20 and the Jubilee Way so there is no need for other than local traffic on the London Road.
Why not turn the road from the Maison Dieu to Cherry Tree Ave into a single lane using either side for pavement/parking/trees/cycle lane/benches/cafe seating etc with a 10 (?) mph limit on the road.
Property is dirt cheap along there and without the traffic you would find young families buying up housing which is truly affordable (unlike Whitfield or the DHB's plans) and gentrifying the whole area.
This sort of thing has happened and is happening all over the country - why not Dover?
