   A good place to start is education on the science. There’s got to be lot of history and ideas a search away. If you had the time to grow a natural barrier there’s nothing more natural, that works and looks good as well.

   I have seen the commercial kind lining the hiways through cities and they go from butt ugly to, on rare occasion, well I guess it works.

   Best of luck !

   The best way would be if the highway department put one in on their right-of-way.

   As Calvin points out, they do tend to the utilitarian side of things to look at.

   You might be better off improving the tightness of your house, or a small area you would like protected from the highway noise.

   https://www.virginiadot.org/projects/resources/noisewalls/Statewide_average_barrier_cost_.pdf Five years ago, the average cost was $42 per square foot.

   so if you needed a noise wall 20 ft tall, 2953 feet long, would be 59060 square feet.

   $2,480,520 (which is why the highway department is not likely to put one in unless you can make a good case.)

   That would buy a lot of new windows, external sound deadening insulation and siding, sound deadening internal treatments, berm walls and landscaping near the house.
