I still owe you some description of Marseille.
The most famous road in Marseille is the Canebière. It divides Marseille in north and south, there's a famous (French) song about it and it's right in the centre. It's also one of the few real tourist attractions.
It's not, however, very beautiful. Like most of the rest of the city it's half dug up and half full of rubbish. Too many cars, too. The city's attitude towards construction works seems to be something like this: Fence off everything that might be a construction site, then dig it up, then leave it as it is for ages. I think this is one of the few representative photos of Marseille centre you'll find on the web.
This is actually a road sign explaining the special rules for the bus that sells pizzas.
