    Can’t be done, there are an odd number of bridges to the east giving you an impossible arc to walk over all of them without crossing your path.

    There was an engineering/mathematical theory for it, but damned if I can remember what it was after all these years.

    Impossible in two dimensions – but if you cut it out, roll it into a tube with the top edge stuck to the bottom edge (three dimensions) – you could be in with a chance.
