I’ve been noticing new bike lane markings around the city. The attached picture (above) is looking East on Columbia Road from the intersection of 18th Street, NW, and shows a neat new green bike lane marking. I like them. As a car driver, I find these marking much more useful in identifying bike lanes from my vehicle.
My questions: Why is the lane marked only up about 30 feet, or will the lanes be only close to intersections? Will all lanes be marked like this throughout the city? What are the stripes for at the beginning of the other end of the marking?
