Finding you way to the top of a Gap

One thing to notice on these pictures the Roads with hashed outlines would be similar to 3 track (three wheel Tracks) roads in the USA. Roads with No hashed lines would be similar to twin track (two wheel tracks) Roads with center line would be 4 track roads.. All of the above would have auto and in some cases Tour Coach traffic comming the other way. Look in the distance on these pictures as you can see the road as it winds it's way Up/Down the gap.
