I'm also happy to be getting a crosswalk at Franklin (badly needed) and a chunk of Cobble Hill's useless no-trespassing-signed green space opened up to public use.
Edit: And a sidewalk down New Washington! I'll actually be able to walk the kids to see the dogs without dodging trucks from the light industrial down the street.
And, if the Friends of the Mystic to the Charles Connector have their way, we'll also be getting a grade-separated bike path along New Washington, from the three-new-developments at Sullivan all the way to Brickbottom and beyond. They have a little information on their website here: https://mystictocharles.weebly.com/
