Many years ago, in the 80s, when trucking to Italy every week, instead of using the Perifreque around Paris we started using Senlis-Meaux-Melun- Fontainebleau & Nemours. Then that got too busy too,now the Disneyworld is on that route, so we then started using St Quentin-Laon- Reims- Troyes& Dijon, which I believe is now all Autoroute. But Paris was a real no, no, unless you could hit it between 0100-0400 as Norfolk Mike says. But this often meant "bending the tacho"!!!
