It's springtime, which is also street painting season. Recently, as noted in the comments, Alexandria installed on Commonwealth Avenue, what I believe is, the region's first bike box. [seen in the photo at right].
I also noticed during my bike ride last night that DDOT, as foreshadowed, has installed new bike lanes on 11th St. NW between Massachusetts Ave. and just north of O St. NW. This is a real road diet situation where they changed the street from two all-traffic lanes in both directions to one all traffic lane and one bike lane in each direction and a center turning lane. I know they aren't done painting yet, but the new road pattern ends abruptly at the alley just north of O St. If you're driving south in the left lane, you'll find yourself driving suddenly half in the median and half in the traffic lane. I hope they're planning to address this.
Also is there now a bike lane on Euclid? I think I saw that too.
Finally, it appears that DDOT is going to build the Pennsylvania Avenue center cycletracks without bollards or background paint - just the lines - because the Fine Arts Commission said no, and there is really no appeal to that. I guess I don't understand why that is less in keeping with the artistic nature of the area than the road itself.
