These green avenues aren't roads at all, - they're power line firebreaks, and look terrible. It's easy to make them go away though, - and this seems to work in both FSX and P3D2:

Make my green lines go away.

Brilliant .. and I thought that was used for the horses , seems the big 'O's forums are more open to constructive comment these days ...

I think if you follow that thread all the way through, or it may have been another (!), but there is also a tweak to adjust the width of the borders to the roads which also makes a noticeable difference to O-Vector. I used both tweaks, and I think the view is better for it.
Cheers

Thanks Jeff, - I'll check that out next time I use Vector. It can look a bit weird with those random wide corridors.
