The Kurilpa Bridge is 1540 ft long and 20 ft wide. It was completed in October of 2009 at a cost of 63 million dollars (or about $2000 per square foot). The bridge includes a canopy, solar cells, viewing and rest areas, and a nighttime lightshow.

"The structural design achieves the unusual appearance of a seemingly random array of tensegrity elements”
That reminds me of the Bird's Nest (National) Stadium in Beijing which appears to be randomly wrapped in steel, but was actually carefully designed and analyzed. The Kurilpa Bridge is a similar kind of design that gives the appearance of randomness that actually requires a great deal of effort. Perhaps that's not such a bad thing.
