That road looks good!
Here is a good one.
I generated a route (call it A to B) and then another (B to A). The routes are identical other than one being in reverse.
Yet when you look at each, they are both routing in the same direction (A to B)...so you look at route B to A and invert it so that it matches what I want to do and then route A to B is backwards and showing the B to A routing.
Go figure!
Try this: In BaseCamp, created a short route from point A to B.
With that route highlighted (left click) then right click to duplicate
Now right click...Invert route.
Both should be named and displayed in your LIST under a Folder .... Both will have proper arrows.
Hope this helps!
