A very tight fit.

I live in Westwell and journeys to Maidstone or Sevenoaks take much longer since I avoid the M20 and Brock. The Bock lanes are far to narrow and being over taken by a huge lorry which is exceeding the speed limit, because I was driving at 50! That one experience, with my Grandson in the back was enough. Now it is always A20.

Highways England have taken the easy solution and have done nothing to explore other answers. It is now so bad that even my MP doesn't answer letters on the subject; poor chap trying to defend the indefensible.
