The title says it all. This is from a old 3.13 save under 3.17. It is easily noticeable that I'm using BUG and Blue Marble:
Spoiler :

I use no mods and I'm seeing ancient era roads for the entire game. It's a bug.
There are Ancient roads in modern age because 3.17 changed XML file Assets\XML\Art\CIV4RouteModelInfos.xml. Paths to graphic files for modern age roads refer to old-style roads. I just edited these paths, so now they refer to modern-shaped roads. As it was in 3.13.
Place this XML file into "BtS\CustomAssets\XML\Art\" folder(recommended) or replace the original file in "Civ4\Beyond the Sword\Assets\XML\Art\" folder.
RAR archive file format .Thats a rar file not a XML file.
