Depending on how close or far your building is situated from the actual road, you may, (and probably will be), wasting your time trying to deaden the sounds coming from outside, in any really appreciable wayIf you have lots or windows those would have to be covered over, buy not touched, walls the same, because when you build something against a wall or window or whatever is transmitting the sound into the home, you simply add to the speaker, so to speakContact means sound transmissionIn a truly sound proof environment, there would be two walls built approx3 - 4 inaway from one another and each insulated, with foam or fiberglass, your choiceThe thing that makes it sound proof is not having any part of the area that's exposed to the sound actually touching the inhabited areaWithout the contact for transmission of sound, it takes an extraordinarily loud noise to even be felt, let alone heardSo, in order to really sound proof your place would require dummy walls that you could take down and set up with ease, each night to keep out the undesired soundsAnd then, of course, you get to the where are we going to store these things during the day when we don't need them, problemI can say with absolute confidence that if you try to ignore them as much as possible, after a while you won't even know the traffic is thereIt will even get to a point, in the future, where when you are somewhere that doesn't have that level of noise, you'll miss it.
you get what you pay fordynamat may be expensive but there is a reason whyIts the best at what it does.
