Excerpt from The Science of Road Making: Construction and Maintenance of Roads The Romans built all of their roads in perfectly straight lines, up hill and down, at a very great expense, as being absolutely the shortest distance between two points. At a later period in history, it was argued that a road must be winding to be agreeable, and many were so built only for this reason. The modern road builder or engineer in general, ignores any such considerations, and has for his aim only to achieve the most, at the least present and future expense. As regards curves in roads in a hilly or mountainous district, we have then the rules never to make a smaller radius than 20 feet, and that only in extraordinary cases. On roads where long log ging or other wagons may be expected, the smallest radius ought to be 50 or 60 feet; and, in general, 40 - 45 feet is none too much.
