Sydney Harburr Bridge was Paul McDermott’s IPP exchange gift at the 2007 IPP. The puzzle was made by Paul and Brian Young (aka Mr Puzzle) and I think it’s inspired as an exchange puzzle for the Gold Coast IPP – the overall shape is absolutely representative of the iconic Sydney bridge, and the detailing on the puzzle is unmistakeably Brian’s.
As a puzzle, it’s a combination of a pair of burrs sharing two bars in common – the ones that form the span of the bridge. As Brian’s burrs go, they’re reasonably straight-forward. (Heaven alone knows how this thing would have turned out if he’d tried to put a Mega-Six on each end … I’m not sure that would work given the interference necessary … but if it did, I suspect that very few of them would ever be reassembled!) The only real complication is the need to build a couple of mirrored burrs concurrently so that they both end up locking together at the same time.
I really like the look of it – it’s unusual and ‘not just a burr’ - the silky oak it’s made from is also quite striking – it’s not likely to keep you awake at night trying to solve it, but think it’s a nice addition to any puzzle collection.
Brian still has them for sale over at Mr Puzzle if you’re interested.
