Bike Route 517Bike Route 5

What are these signs? I can see they are some kind of bike route, but who put them there? Where can I find out more about them. Are there maps showing the routes somewhere?

Both of these signs are within two blocks of my home. I’m not surprised to know a bike route has been planned there, after all, it is the historic Erie Canal. The Adventure Cycling Association’s Northern Tier Route comes through here as does the NY Erie Canal Bikeway.

But, I see these little green signs all over the place, and no one seems to pay them any attention or know their significance.

If you know any more about them, please let me know!
