Thank you for pointing that out!
That was what I was missing all along!
Finally finished the game!

Nevermind, there's an icon in the top left after you run a level that tells you if there is an interchange picture and what score you need to get it.

Is there any way to intuitively figure out which maps have interchange pictures? It's kind of frustrating that they don't even hint at which maps have pictures, nor do they tell you how many points you need to get them. If someone were to play this game without any help from the internet they would just have to arbitrarily improve their score on every map without any guarantee/indication that they are getting closer to unlocking a picture. I was trying to avoid looking up which maps have the pictures, but it looks like that is what I am going to have to do.

Thanks for this great guide, but no matter how much I'm remaking map 55, i just cant seem to get this part of the achievement done. I tried many designs from multiple sources but no luck there either. map 55 is also the last part of the achievement which i need to complete in order to finally unlock the achievement and also finish the game. It would be very nice if somebody could help me with my issue, for which i added some images below. Thanks in advance!

Hey, managed to get a slightly higher score on map 71! Using slightly curved in roads

Could you add the efficiency score required to unlock each one, that would be handy.
