I had an idea of making more fun less redundantly designed level for a racing game, i have core mechanics and ui of the game sorted out but i m confused where to begin with the levels and how do i structure them. link of any sites that focusses on this would be greatly helpful.
You could try building some roads with some tools like:
Then you can use some more assets and props like:

All in all don't expect to think of a complete level/scene, go bit by bit and your imagination will follow :D
You can also find more tools for the terrain here: https://assetstore.unity.com/tools/terrain?category=tools%2Fterrain&orderBy=4
