Aqueduc looks very similar to the Pontoon puzzle with a mixture of a rectangular plate with 2 very simple H shaped plates at 90 to it and held in place by another 2 more simple burr pieces. The difference is that the puzzle is an extra unit wide which makes the disassembly quite a bit more complex. Again, I solved it the first time using rotations and only Burrtools revealed that 31 linear moves were required to remove the first piece and another 3 for the second. The stick burrs can only be removed at the end by rotation. For me it adds to the puzzling delight that it can be solved with rotations as well as using linear moves. Pontoon and Aqueduc make a perfect pair for the collection.
