Stuart,Just had another look at the website it shows the A85 on both sides of the A10 towards Tours on one side and Bourges on the other but shows both bits as not complete and the site is showing todays date.I might go back onto it and see what the webcams show in that area.
It also shows the A89 as incomplete to the west of the A20 towards Perigneaux any ideas if that is correct or is that open.I know this is some distance from where you are but you may have been told.
