I don't believe I've ever included a photo of the multi-use path along Pennsylvania Avenue SE east of the river, even though it's been open for a couple of years now. The project represents one of the road diets that the National Capital Region Transportation Planning Board approved this week (even though it's already complete).
This was built as part of the Pennsylvania Avenue Great Streets project. The original plan in 2007 included bike lanes, and when it was changed in 2009 I was a little critical of it. The 2009 design included a diagonal crosswalk at 28th with an exclusive bike/pedestrian crossing phase, but that didn't make it. Nor did the trail NW of 28th, which is too bad. Nonetheless, the MUP here is a pretty good feature and it makes Pennsylvania bikeable in this direction - which I would not say it was before.
The trail is really only needed going SE, which is almost entirely uphill. Then the trail becomes a climbing lane. At 10 feet it's about the same width as the CCT, and there's much less traffic. There aren't too many crossstreets, so it doesn't have the safety issues associated with sidewalks - and going uphill slows one down to a little over a walking pace. Downhill, it's easy to ride in the street.
But heaven help anyone who decides to go downhill on this path. I can get easily up to the 30 mph speed limit going down Penn (not that anyone else is) and that kind of speed is not safe on this path. DDOT should put sharrows on the downhill part of Pennsylvania to encourage its use - and even consider marking the trail for uphill bike use only.
I still wish they'd gone with a sidewalk, and put in a buffered bike lane on the uphill side instead of the path (with sharrows going downhill of course), but this is still a great improvement over the old road.
