I construct my industrial area in a elevated area, but fortunately, many areas are straight or leveled (or almost), it helps me to take advantage at the most of the area, except areas little too high (that I can level using extra landscaping tool). Anyway, the case I'll tell you are in the areas close or into the high areas, I was trying to construct a standardized area to the industrial buildings, but the network anarchy try to elevate the road until too much, without I ask, too much that many times it doesn't start at 0 m (or correctly leveled with the terrain), which means it tries to make a bridge, while when I use the original road tool, it doesn't try to elevate too much the road and obviously isn't capable and try to construct a bridge, so many times it's more useful than try to construct at the bridge/elevation mode without I want and without I select these modes (and obviously is boring and a lose of the time disable network anarchy for it)
