3d - How would I implement an endless road the player runs down?

I want to create the illusion that a man is running down a long road i.e. this pic

If you have played Temple Run on the iPhone, it's the same principle, but instead of a temple it's a normal road.

I want to know how this is implemented. For example, do I just repeat this road image in a loop?
