That is a good question of which I do not have an answer. The best place to inquire about sound barriers nearby busy roads would be the State Department of Road, I would imagine. This is just a guess. This appears to be a very nice home. Do you have an agent handling your side of a purchase? If not, having a Buyer Agent serves your best financial interests and the good news is you can have representation at no cost since agents are paid by the seller.
I welcome the opportunity to serve as your real estate consultant and advisor. I was licensed in 1986, started part-time in the business and went full-time in 2000 when I started selling for a builder in King Farm. I also grew up in the custom homebuilding business so I know a lot about construction.
Let me know if you'd like to take advantage of my expertise to serve your real estate endeavors.
