I like the traffic flow with this, but I've run into a bug with it. When I loaded my game after placing a couple of these, a couple of the pillars ended up glitched and causing a huge scar in the land (http://puu.sh/hHZXJ/68c330e494.jpg) . I deleted and remade the road sections but the pillars are glitched and still there (without road on top of them). Hopefully one of the bulldozer mods will be able to take care of the pillar sections but if you know why it might have done this perhaps you can fix it for future users.
