No i described an area of a town with one main way in to town and one main way back to that area.Your comments in this post change the parameters of the original post.
Initially, you describe a town with 1 main way in and the same way out.
That almost never describes a growing community with an affluent population.
It almost always describes a small town that is stagnant on population growth, which in turn means taxes, housing, and business are also level or down.
This is a real world example of a town experiencing this. It’s affluent. It’s more than 20,000 people.
