I'll take the opportunity to comment as well! Under city code, these power lines on Newbury Street should have been put underground during the construction process. The developers applied for, and received, a waiver from the planning board so they do not have to bury them. Their reasoning was simply that it's expensive. But they would have forged ahead with the development even if required to underground the lines, so in my opinion the city blew a rare opportunity to get even a small stretch of utilities put underground.
What blows my mind is that these expensive new homes and offices on Newbury Street are going to have poles and wires literally right outside their windows. I still laugh every time I walk down India Street and see the circus of wires mere feet from the windows and balconies of all those expensive condos in the Mason Block building.
