Highway barriers block sound and pollution

This story reminds me of how close we seemed to be a few years ago to getting the Mass Pike to build a barrier wall along Lincoln Street. Newton, Framingham, and many other towns have them and the Pike officials told us that we were next on their list. Then the tunnel ceiling collapsed, a new governor was elected, the Pike administration changed, and our hopes of getting this wall slipped away.

Maybe this newfound public health rationale will someday help make it a priority.

Highway barriers block much more than sound - The Boston Globe
"The research found that the barriers do more than protect neighbors against unwanted sounds. They also keep pollution away, reducing it by more than 50 percent on the other side of the barrier."
