These are the changes proposed by the Great Streets Initiative, an infrastructure redevelopment program that was supposed to have started this past fall, but has been pushed back again. I also just noticed that they put out a very comprehensive design report (images, renderings, examples, descriptions) in November, which you can access Here - definitely check out the link.
The thing that frustrates me the most at this point is that there are no plans to underground the overhead utility lines - something I plan to formally argue for in the near future.
