So… I am working on game Left Behind, and the game is post-apocalyptic emotional story game, such like The last of us, or entry point [EP is just emotional].And I’m stuck on the hardest part of the game… ROADS…
I am trying to make something like these
But I always fail… Any ideas how to make an effective road? [sinkholes, trash are already used]
honestly you should (If you got blender) use the knife tool to cut it up and put the road in random places and angles and you should at least try to get barriers made and use grass in order to make it look realistic. I have always wanted to work on a game like this and I wish this helps you. (If you need help I would love to help you with the story design and see the flaws). My discord is at Attacky#0213 to talk more about this
…Blender is a huge problem for me… My computer doesn’t stand blender and barely does roblox 
Just use a free model, sometimes free models aren’t that bad you know.
…The free models don’t look too realistic.
Apply grass on top of the roads and create gaps/holes using decals. Play with the lighting, try to make it messy. You need to feel how it looks, my suggestion is to check out those old elite builder (group) places where they only used parts to create an apocalyptic environment.
Enviroment is easy, lighting too… But building isn’t… ;-;
Takes time and patience, play with it.
…Decals are very hard to find and roads are full of 'ROAD ROAD ROAD ROAD ROAD ROAD ROAD’s…
This is all part of building, create your own decals or effects. Try making holes with unions perhaps
Here, I made this for you in 5 minutes. I cut holes with unions, gave it depth and contrast. Added grass and rocks to fill up the space. @AzimuthBecameReal
Heres a showcase, its exactly what you are searching, I notice that the developers used some free models, but its looks amazing! here is the link:
