Here are a few shots from my favourite bridge in Brisbane.

According to Wikapedia "Kurilpa Bridge is the world’s largest hybrid tensegrity bridge.[5] Only the horizontal spars conform to tensegrity principles. The Kurilpa Bridge is a multiple-mast, cable-stay structure based on principles of tensegrity producing a synergy between balanced tension and compression components to create a light structure which is incredibly strong.[5]

The bridge is 470 metres (1,540 ft) long with a main span of 128 metres (420 ft) and features two large viewing and relaxation platforms, two rest areas, and a continuous all-weather canopy for the entire length of the bridge.[6][7]A canopy is supported by a secondary tensegrity structure.[5] It is estimated that 560 tonnes (620 short tons) of structural steel including 6.8 kilometres (4.2 mi) of helical strand cable are incorporated into the bridge.[8]"
