What is it you think is the problem with the motorway ring road around Bruxelles?
If you think it's going to be horrible around Bruxelles, take the motorway via Lille instead.
Still not sure? Take the motorway via Antwerp / Gent as an alternative.
Via Michelin's excellent website lists:
1. Via Bruxelles at 3 hours 26 minutes and 295 km
2. Via Lille at 3:36 and 311 km
3. Via Antwerp at 3:48 and 324 km
All on a Sunday morning. There is nothing to chose between them, except 22 minutes and 29 kms.
http://m.viamichelin.fr/# A great, free website with excellent assorted scale and detail maps built in, including the 'must do' green lined D roads, for those that would rather rip their eyes out than ever use a motorway.
A more interesting route? A very quick look at something approaching a decent map will tell you that genius suggestion will take you miles out of you way, but here goes:
Liege
Dinant
Rocroi
La Capelle
Or break off via Chimay and Avesnes
Cambrai
From Cambrai, it's the agony of whether to take the motorway or work your way a bit further west inland.
It's now Sunday morning, the thread having started just after 8pm on Saturday, for a journey to be made sometime on Sunday. The sun is shining, at least it is in Verdun and it's time to bite the bullet....
