So for me, I like to build bridges, and roads, so they don't break the terrain. Unless its a mountain, in which case I will tunnel every time.
If you go to the road, and follow it south, you will see where the bridge needs to be.
I would hold off though. I can put a chest near that point for you, with the building materials I am using for the road. That way its all uniform.
also, What are the thoughts on the road I built so far? I tried to make it stand out from the surroundings. When I get to the E-W section, it will be made of different bricks, that way if you don't have a map handy, you can still know which road you are on.
If folks don't like the look of it, I will change it.
