As any bicyclist can tell you, a bumpy ride on cobblestones is no fun. In NYC, the DOT has implemented its first granite bikeway on one block of Varick Street to make it easier for cyclists and to keep them off the sidewalks.
You will almost never see me on a sidewalk in NYC for any reason, but I confess, I have used the sidewalk for this one block in the past. The smooth granite is a great idea.
I got to speak with Nick Carey, a project manager with NYC DOT's bicycle program, about how the project came to be and how the department might use the same idea for future bike routes.
