Highway construction trend

We’ve talked about solar panels along and embedded in highways. We’ve talked about EV charging roads and sustainable concrete sources. But here’s a new one. How do you beautify infrastructure and also improve communities? Look to Mexico City. The city is adding vertical gardens to highway pillars that clean the air and beautify the city. 

There’s also been a lot said lately about the use of moss as a highly efficient air cleaner. Welcome moss covered pillars that could clean the air and lower temperatures. @thebrainypedia
