Columbia Heights Streetscape Project has moved onto the sidewalks in the area too. I've seen construction on 14th Street and Kenyon so far, with other ones already done or in the works.
It seems like they're widening the sidewalks, though that might just be an optical illusion based on the new pavers and such, though the website doesn't say anything about widening (which would thus mean narrowing the streets).
But anyway, the new pavers look good. Your thoughts?
