Check this out..Flight1 will be coming out with USA Roads that can sit on top of any terrain for USA.http://www.simforums.com/forums/forum_post...p?TID=7507&PN=1Hopefully... when getting close to the highways.. the roads would be more detailed with maybe even some Interstate signs and some generic Green and white direction finders.

There's a kinda popular thread already running on this very topic ;) .. looks interesting, certainly.
