Building a more seperate bike lanes like this in NYC is a great idea, but the lanes need to be connected to a bike path grid (not just some random 7 blocks). Let's hope this is a start.

NY really needs more bike lane like this on the Eastside. A seperate bike lane like this design on 1st ave between 39th street and 54th would be an excellent 1st step in connecting the Greenways on the East river and would bring a lot more bike traffic to the East River greenway bike paths.
