If one stands in front of the house they will find that the noise from the road actually "bounces" inward to the houses across the street and in further inward. The fence is a very good thing for direct relation to the road.

DeLuna has villas up against the turnpike. I wanted to check that out one day and found that to happen. Across the street I heard it. Further in I could hear the turnpike. If you are used to busy road no problem.
