Assuming the route is perfectly circular, the difference would be 2pi
multiplied by the distance between the two passageways.  If that
distance is 15 feet, then about 94 feet.  I've not contemplated the
effect of relaxing the circular assumption; don't believe the
relaxation would affect the difference.
