I was stuck on 339/340 a few days ago too on the 360 version; make sure you travel as far up on/off-ramps as you can, hugging the guardrails if you have to. It also seems like your count increases when you explore the larger off-map places like the Abbey and the Airfield, so try to do those too. When I still had the one left, I simply started Fast Traveling to each outpost; the achievement popped at the loading screen between them. Even though the little nubs all looked white on the map, that’s what it took. Good luck!
Lastnight I went through everyone’s suggestions. Still won’t activate. I’m not restarting the game if this is the only way to fix it. Also this website isn’t tracking my reward points which I hope doesnt mean a reset of the game and start over. I’m lvl235 and completed pretty much everything except I’m only at 4/10 races for every track. Restarting isn’t an option that I’m willing to make
The last option would be to record yourself walking through the entire map or pictures and then we can help out and give out some extra eyeballs for you. Sounds like a lot of work, but it beats starring at the screen again.
Just waisted another 1+hrs draging guard rails all along every freeway on/off ramp. Lastnight I spent 2hrs driving down every street in all the cities, even all the little hidden alleyways. Went to the airport and drove over every piece of paved area, even under the the little tunnel. Drove in/around the ruins. Been to every hub and dragged every wall in or around the hubs. Every hub that has a bulb shows on my map. Drove around every little triangle shaped intersections and round abouts. On the freeways I’ve driven both sides with 3 passes each side (far left of lane, middle of lane and far right of lane)
I’m pretty sure I’ve exhausted every inch of road multiple times over. My only option is to take pictures of my map and post them. TV is big enough to take big clear pictures but when I look through the camera on phone you can see the waving of the tv. It’s a 65in. plasma so might be catching waves through the phone that aren’t visible to the eye. There is no way to take screen shots on Xbox 360 that I’m aware of, that would be easier & better. Going to take some time to take good pics of all the roads with map zoomed in but think it’s my last option.
I had this same trouble but for me, I saw a little bump of a road (more like a driveway) on the left side of the construction site “Zone Industriale” just south of Montellino that was white but going there anyway, it was the final road I needed, guess the game never caught it even when I drove past there like 1’000 times.
Hope this helps people.

As mentioned above by someone else…when I finished my map, it was a highway on-ramp that was missing. Can see it not filled in on the map, but it’s very hard to spot. Its a really tiny area thats not filled in on the map for it. I drove myself nuts looking for the missing spot. It was so small an area and odd shaped, i was not even sure it was what I had been looking for until i got there and it told me i had driven all of the roads.
Just to say that I’ve spent hours scratching my head and stuck at 339 until I read the above post. I went and had another look at the map (even though I’d looked at it carefully from a few inches away already) and found a handful of grey pixels I’d missed. I never would have noticed it in a million years!
Well after finding out tonight that on the Xbox 360 side of the house that our achievements in the game don’t affect your Forza.net reward points and account I don’t feel any hury, care or want to worry about achieving anything in the game anymore. It will just be waisted work and hours for nothing. Thx for the support from everyone though, maybe some day I’ll want to find it for gee wiz but other than that I’m turned off on this game now knowing I’ll be waisting countless hours and hard work for diddly squat!!
This is a common problem with Xbox 360 owners. I have driven every single road and yet the game is stuck on 339. I can’t get the achievement. Can anyone list me common misable roads? I am getting really angry about this issue.
It could be anywhere …
Try going to the hub entrances and swerving around the inlet of the entrance point I had three of the hubs I had to do this with to unlock all roads. Other places can be an on/off ramp or a triangle on a turn or the opposite side of a highway.
Some glitches I have come across are
-
There are a lot of holes in this game you can do a jump and lose your points and time stunting by falling through the screen i.e. I did a jump and was buried up to my hood many times over sometimes you can drive out other times you get reset.
-
There is a speed zone in an event race and I tripped finding the zone but DID NOT register a time and made it difficult to determine what zone was registering not complete when all zones were lit up as complete. (I will try to post the name later I believe it is in the lower right area of the map)
-
AI TRAFFIC cars with NO lights on at all in the dark driving they flash their lights at you when you are about to hit them head-on as they would do in the day mode … other AI TRAFFIC cars may have no lights at all PARKED in the dark on the track and not moving that do not turn lights on at all.

I seen this on here by another gamer but they are 100% correct you can lose total sound to YOUR car especially if you fast travel and if you enter a skill and back out your sound will come back on … all other sound stays normal except the vehicle you are driving.
Hello all,
First post here but not new to Forza at all. My problem is I have Horizon 2 on the Xbox 360 and out of the 340 roads I have driven on 337 of them. When looking at the map to find these last three I have a hard time and appear to me that I have covered everything. Any ideas?
BTW I really wish they had the 2015 Mustang on the 360 version, I was really excited about that but it didnt happen.
Well sirs I finally stumbled onto my 340th road!!
Try the roads leading into the airport, chapel, and warehouse area. I missed I sliver of road at the warehouse, and triggered it in king mode.
Yes I am playing on the 360. No it is not as good as the Xbox one version, but if you don’t have a One its still a damn good game. So the problem. I have, or at least think I have driven on all the roads, yet it say 339/340 driven. I have scoured the map for an little piece for about 1.5 hours now. Nothing. I doubt its me either, because it took me less time to find my last few missing pieces on TDU 2. Any one have a fix? Having this problem at all? How about on the one even?
It might be a road that looks completed but has a small portion that is not completed and that portion is small enough that you can not see it.
Also I must wonder: Why does the 360 version get more roads? some of those trails in the Xbox-one version that lead into the woods could definitely classify as roads in my honest opinion.
I noticed on the motorway and a few other long roads that apparently i driven a road when i still got road to cover. Could explain the 340 i curently at 312 not gone out to do them all yet. I expect missed roads to be under motorway bridges loads of little roads that might not show. I dreading getting to 339 I struggled on fh1 with a missing road. (i cut a corner)
I spent an hour last night on the map screen, fully zoomed in with all icons off, searching for that last tiny sliver of gray to clear for 100% road discovery. To no avail.
It can’t be this hard; I got 100% road discovery in TDU and TDU2, and they had much more extensive road networks than FH2.
Anyone got any tips to help?
Edit: just noticed there is another thread for this. Sorry all.

Bah, I’m having the same problem in the Xbox One version. 314/315 roads driven. Driving me mental. 
Ok, I just collected the final 3 roads all in the same race. it was the bucket list #2 with the Ferrari 250. Its a pretty long drive that covers alot of road. Before this race I had done all the usual stuff lookjng for the last roads. Nothing showed. No dark areas, etc. I saw this bucket list, thought coo,l big payout great car, easy. About half way thru I saw a tiny grey section on the road, hit it and picked up #338. Kept going and about another minute all of a sudden I got #339 the human gps cheevo popped and then #340! Now the last 2 didnt even show up on the map even as I was driving over them?! Weird. Either way done and done. If you’re having trouble with the last couple roads its worth a shot. Worst case scenario, its a big payout with a cool car.
