The Cambridge Colleges that back onto the river all have bridges linking the two sides. Kings bridge is a fine work of stone sculpture, understated yet eminently suited to its purpose. Clare has a stone bridge, as does Trinity. John's, being bigger and richer than most of its neighbours, has two. One is the so called "bridge of sighs", not to be confused with a bridge in Venice of the same name. At John's it's sighs of anticlimax.

Queens has the Mathematical Bridge, which is made of wood. The story goes that this bridge was designed by Isaac Newton with interlocking pieces that didn't need any bolts to hold them together. During World War II, the story goes on, the bridge was dismantled to save it from stray bombs meant for Coventry or London. But when peace came and with it time to rebuild the bridge, the builders (and obviously the top minds at Queens) couldn't work out how to put it back together.

The story is, of course, a total fabrication - or at least only as true as the one about King's Bridge being built by the Easter Bunny - just another Cambridge Myth thought up by an embarrassed Queen's student trying to cover for a cheap and nasty bridge.
