Hi we are going to a site near le mans in a couple of weeks,and as i understand it there was a fire on a bridge so i have been googling, and reading different threads and I am hoping the route that I have chose is ok, diversion is A29 the A151 direction
of rouen then A150 then pick up A13 then south to A28 will this be alright with the caravan in tow, thanks.
