The underlying technology hasn't changed any. As an exercise, you can try replacing "2006.html" with "new.html", but that's actively beta. (Well, "actively" as in "it's broken in a couple of ways" more than "I'm working on it.") The mile markers work there, and I think the colors in the color modes are a little more functional. I can't think of a reason off hand why this route in particular would cause problems, particularly if you have the color mode set to "nothing".
