This is the Da Vinci Bridge in Ås, Norway. It is called the Da Vinci bridge because it is a scaled down, modernized version of a bridge that Leonardo Da Vinci designed for Sultan Bayezid II of Constantinople in 1502. While Sultan Bayezid II never built the bridge, intended to span 240 m across the inlet to the Bosporus called the Golden Horn, an artist in Norway, Vebjørn Sand, decided the ancient artist/engineer was on to something. The Da Vinci bridge in Norway serves as a footbridge over the E18 highway. It is also part of a burgeoning effort to use local artists and materials in the design of public works projects to give them a unique, local feel.

The original is a very very modern looking design.
I saw the traveling Da Vinci exhibit at the Royal BC Museum in '99, this was my favourite piece.
