Developing this corridor makes such sense. Build a light rail/streetcar line from Broadway to South Station via the Seaport & Marine Industrial Park, and you have a real neighborhood and smart growth. The corridor between Andrew and Broadway can be office and higher density residential, while the greater South Boston peninsula can be a somewhat lower density residential that supplies the offices and business of the Seaport, MIP, and Andrew/Broadway corridor. We can learn a lot from Portland, Oregon. I travel there quite a bit on business and they've used the Portland Streetcar to connect neighborhoods while still maintaining the MAX system as more of a regional metro.
