when i cycled the liverpool to leeds towpath a section between bridges had been firmly closed off near aintree by what seemed to be a local builder repairing a brick wall , had to negotiate up a narrow makeshift spiral staircase ( like an old fire escape), complete with bike and panniers while being surveyed by the local youth , the numerous motorcycle barriers from that point was just a little tricky, biggest hazard was the wet muddy sloped embankments between skipton & leeds shod with 27c Michelin conti contacts an fully loaded panniers, oh an some nesting swans, but then its the variety that beats tarmac touring.
