The puzzle is indeed solvable if you are allowed to pass through a line
lengthwise instead of merely crossing it.  (This is what the statement of the
problem seems to imply.)  I won't attempt to draw a solution on the terminal, 
but it is fairly easy to find once you know that that is the secret.  If 
tracing a line lengthwise is not allowed, then the "Seven Bridges of 
Konigsberg" reasoning applies and the problem is impossible.
