Although the house is set amid ideal tropical landscaping, and you can't see the highway from the house, it is right on the other side of the front hedge. I don't remember any details regarding this in the ad. The highway around the island is quite busy as you may need an entire minute just to get out of the driveway (depending on the time of the day). The sound of the highway? My sister said, "Its noisier than Portland!" Sirens, beeping, trucks, etc.
