I know that there's a new highway that's supposed to be opening this year, the 40D I think. It's supposed to be a crazy highway, using 60 tunnels and 115 bridges, including one that's the longest cable stayed bridge in the world - I saw some pictures of it being constructed and it looks unreal. But hopefully the new highway will be taking pressure off of the older one, leaving less truck traffic. Is the road quality itself bad on that old highway? I guess ten years ago things may have been different as well - I just know that taking the 200 south from Mazatlan was not fun at all on a bike - that was some of the worst riding that I experienced in Mexico. The traffic was awful. I think I'd take great scenery with dangerous corners and ledges over that heavy volume of truck traffic and no scenery... but then again that's easy to say from the comfort of my chair now. Flying over a ledge into an eternal abyss, and I'd be second-guessing that...
