The JK Bridge in Brasilia is a lesson in elegant bridge design. The three huge diagonal arches over the deck of the bridge give the structure an amazing visual fluidity.
Thomas Heatherwick's award-winning rolling bridge is an ingenious addition to the grand union canal system in London and is unique. Unlike regular movable canal bridges, the rolling bridge curls up to form an octagon by way of hydraulic jacks to let ships pass.
This bridge supports two pipelines; one gas, the other oil, across the extremely deep gap in Papua New Guinea. If this were to be officially recognized as a vehicular or pedestrian bridge it would rocket to the top of the 'world's highest bridge-span' with the pipelines at an impressive height of 1,290 ft above the bottom of the gorge. By comparison, the current highest bridge span belongs to the Royal Gorge Bridge in Colorado, hanging a mere 1,053 ft above ground level
This incredible vertical lift bridge is in Rouen, France, whose spans weigh 1,200 tons each but can be hoisted 180 ft vertically in an impressive 12 minutes. The angular lift structures at the top of each tower weigh 450 tons each. The huge vertical lift allows even the largest cruise liners to sail through.
'Henderson Waves' is Singapore's highest pedestrian bridge and is at the 'Southern Ridges,' a beautiful 9 km (six miles) stretch of gardens and parks. The deck of the bridge is made from thousands of Balau wood slats, perfectly cut and arranged, and along the length of the deck a snaking, undulating shell forms sheltered seating areas on every upward curve.
Beipanjiang River Railroad Bridge in Guizhou is an enormous railway bridge that was built as part of the 'Guizhou-Shuibai Railway Project'. Connecting two mountains over a deep ravine, at its highest point the bridge's deck sits 918 ft above the ground. Parenthetically the bridge connects two of the country's poorest areas.
