Here's one picture that shows many of the elements of the new Beacon Street bike lanes:
- Wide lane next to parking
- Lane next to the curb where there's no parking
- One of the buffer zones
Updated: The bottom picture is of the westbound lane. (It's late afternoon and the sun is ahead.) The lane ends right at the Boston/Newton border. The foreground is Boston. The background is Newton.
Also, I don't expect the sadness to last long. Newton plans to continue the bike lanes to Hammond (or start them from Hammond, depending on the direction you're traveling).
Here's a detail of a buffer zone.
And, this is the sad end of the bike lanes, at the Boston/Newton line.
