I'm not sure I'd characterize that particular trail as "no traffic" [1]. Large segments of the route you describe are along country roads where you share the road with cars and trucks traveling at 55mph. As much as I wish it weren't so! That'd be so much fun. :)

Perhaps you're thinking of the Erie canal trail (Buffalo to Albany), which is composed of a much higher proportion of bike trails?
