These roads are a great addition and use them quite extensively in my maps as they look so nice and fit in well.
I know that you say that it may not always be possible to have requests granted for road variations elseware but I will ask regardless in case I get lucky :)

Would it be possible to have a 3 lane variation of this road (2 square width still)? I could really do with them on my towns inner ring roads as the 2 line roads suffer from heavy traffic and I like the narrow streets of my towns :)
Anyway, I just thought I would ask regardless.
