Actually it isn't. Do know that a character refered to a legend when speaking on it's length, and he never crossed it himself.

Going by the pic it would seem like Snakeway covers a quarter of the universe.

Which is ridiculous of course as that would make Goku so insanely fast in terms of travel speed that it would be bullshit.

My point is the actual length of the thing is hard to really pinpoint considering the questionable sources.
