Re: What was an "improved road"
In the world of civil engineering, the term "Street Improvement Plans" is still used to describe those plans that show a plan view of the road, indicating the geometrics of the layout and grades, and then a section through the road, both transversly and longitudinally, indicating underground utilities, etc.
An "Improved Road" can mean anything better than two wagon wheel paths on a cleared space. Macadam (asphalt), conrete, brick, cobbles, anything better than plain dirt.
