This photo shows the soon to be painted bike lanes along 4th St. SE (on Capitol Hill). Besides being clearly in the door zone, these future bike lanes are interesting for something else. Right down the middle is a line cut into the asphalt. What is this line, you ask? It's where the contractor painted the lane line in the wrong place - for a normal one way street, not a street with a bike lane. Actually it isn't paint at all - it's thermoplastic pavement marking, and it can't be removed with paint thinner. It has to be ground out, leaving the nice trench you see here. The same thing was done on Rhode Island Avenue in College Park to make room for the College Park Trolley Line trail, but that wasn't due to an error. So why not make the contractor fix the surface - or pay a fine? Got me.
