In 1502, Leonardo da Vinci made a simple drawing of a great, 240-meter bridge that was to span an inlet at the mouth of the Bosporus River in what is now Turkey. The bridge was never built, but Leonardo’s design has been reproduced in a wooden bridge for pedestrians over a highway in Norway. Artist Vebjorn Sand’s Web page describes his campaign to get the bridge built and provides images illustrating how it was constructed.
