When on tour I encounter roads like that quite often. If traffic is heavy I prefer to find an alternate route, if not, I don't mind. The worst road I ever rode on was near the end of my Pacific Coast tour, headed inland in the California Central Valley. It was a 55 mph two-lane highway that started out with a nice wide shoulder. But the shoulder deteriorated until it was gone altogether, and around the same point a barrier was put in place along the center line to prevent vehicles from passing each other. Unfortunately, this also had the effect of preventing people from moving over to give me any room. Traffic was extremely heavy with lots of cars, semis, RVs, etc. To add insult to injury, it was over 100 degrees that day. It was a 20-mile-long nightmare.
