DDOT hosted a scoping meeting last night on the redesign of Southeast Boulevard and Barney Circle.
The above shows the basic idea for Barney Circle. The blue lines are the sidepaths. All around the circle are controlled intersections so that cyclists and pedestrians could move around the circle. Everything is still wide open at this point so the consultants that I talked to were open to the idea of using the eastbound tunnel as a bicycle underpass from the southside trail to the eastside one, and/or keeping the westbound tunnel open for the same purpose. Pushing the trail across the circle seems unlikely at this point.
This shows the basic idea for two of the three concepts. Southeast Boulevard would either be close to L like this, slightly farther away or in a 3rd concept much farther away without connections to 13th, 14th and 15th. These two concepts give cyclists more connections, but for those using the north side path, it also means more at grade crossings.
It was unclear how fast traffic would move on SE Blvd and thus how safe it would be for cyclists in the road. It was also unclear why the road would need to be four lanes, or if it could be just two.
The people I talked to were open to the idea of a pedestrian bridge over the RR tracks somewhere around 14th Street that would give a better connection to the Anacostia Riverwalk Trail.
The design will leave some extra land between the CSX tracks and L street. One idea is to raise the street on a deck and build bus parking or a bus transfer area under the deck. From a biking standpoint this would add some at-grade crossings but otherwise be a non-event.
