You beat me to it Franglais, just come back from a 4 day stint in the UK and was going to post the same when I got home.
Saw/heard loads of info on the overhead gantries and on the local radio today, so here goes:-
Caen northern ring road will be completely closed from 9 a.m ( this is the route that the officials and dignitaries will be using).
The dual carriageway from Caen to Ouistreham will be completely closed from 12.00 to 19.00.
The N13 completely closed from Caen to Isigny sur Mer all day.
The afternoon sailings from Oustreham and Portsmouth will not be running.
And here’s the one that will concern the trucking fraternity:-
From 05.00 right up to 23.00 ALL poids lourd (HGV’s) are prohibited from using ANY roads in Calvados (14)
(haven’t found any details for Orne (61) or Manche (50) yet, but as far as I know there will be no problems in these two departments
