On this side of the world usually it's vice versa. Developers start building on cheap land with little infrastructure. Then increasing population forces government to improve infrastructure decades later. By the time construction is done, it's already outdated and overcrowded.

Even if it happens your way... Is it wrong that an interesting location opens up at the end of new road? E.g. a restaurant or trailhead? Yes, it would increase traffic. But on the other hand, this would also let people do things.
