Hills are tricky with the style of terrain you are using. Since terrain is in blocks, creating a hill like this that terraces a bit would be slow for travel bumping up each step. Are you going to use slopes, or I'm guessing you like the blocks even if they are a bit inconvenient?
Of course though, still good job. I like how the road goes up a hill, and doesn't even follow a straight line, but when looked upon, one can still make out the road. It will be harder to distinguish dirt but I guess that is not so much a bad thing for a less-used road. Again, I'm enjoying myself just watching the different problems you tackle.
This road is made with half-height blocks so you can walk it almost as fast as walking up a slope.
Using slope blocks is really really really hard to get right in these non-straight cases. Even by hand that would be tough to do. I don't mind the block terrain so much in this case... and it will be easier for animated characters to navigate, too.
One benefit of block terrain that a lot of people don't realize is that it provides nice contrast. The slopes are really easy to see from a distance. With smooth slopes it kind of all blends together and you lose some definition... solvable problems, of course... but a block world is slightly more forgiving in this case.
