As recently reported in electrek, Lexington may soon host the first solar panels on highway sound barriers. The installation, first discussed with the Select Board in 2016, will be the first of its kind in the US, and construction is expected to begin in spring 2022. The Massachusetts Department of Transportation (MassDOT) conducted public outreach over the years and have decided to proceed with the trial project. New to the US, projects like this have been deployed in other countries, such as Germany and Australia.
