Sorry if it's the wrong part of the forum, wasn't sure where to put this.
The highway runs along the north wall of my deed (South Novus), and I wanted a flat deed border. So I levelled it out, but would like to lower the highway also please. The tallest part there is 32 tiles steep, it should be easy to adjust it, and the terrain around it to make it all smooth again. I haven't needed to surface mine anything yet, but not afraid of it. I may need to tear up some catseyes and a waystone, but will fix it again after. I will create the catseyes etc before breaking anything, haven't got them yet.
