How to make an object created every second, and "behind the scenes" deleted?

Question

Game development

Hello. I have a scene in which I use a road spawn script - so that the road appears every second, we pass it and it should disappear. I only made it appear, but after I pass it, it does not disappear. I tried to write, but it turns out that it deletes exactly the object that I use to create this very road through Instantiate. How should I do? I want it to only delete what I drove, not delete the road object that the game uses to create further objects.
Right now I just get a message saying that the road has been removed and cannot be spawned.

Answer 1

Throw this script on Prefab Roads.

Answer 2

Instantiate returns an Object which is actually created. That's what you need to remove.
GameObject go = (GameObject)Instantiate(prefab);
Destroy(go);
