The world’s highest bridge

The Duge Beipanjiang Bridge (also called the Beipanjiang Bridge or the Duge Bridge) is a concrete cable-stayed bridge that carries four lanes across the Beipan River. Connecting Xuanwei in the Yunnan Province and Liupanshui in Guizhou, the bridge reduces travel times between the two cities from four hours to just over an hour.

It was a massive construction project, and the designers kept having to move the final location of the bridge higher and higher to avoid caves and cracking in the karst mountains at either side of the valley.

The eastern tower of the bridge is 883 feet tall, which is up there among the tallest bridges in the world. Even more impressive, however, is the huge expanse between the road deck and the river below. The deck is 1,854 feet—or over a third of a mile—above the average water level of the river. For perspective, the Golden Gate Bridge in San Francisco has a clearance of about 220 feet. Chicago’s Sears Tower would fit under the Beipanjiang Bridge with 400 feet to spare, while London’s 30 St Mary Axe (The Gherkin) would fit under the bridge three times over.

Australian engineers quietly changing the world








Australian engineers have created some of the most incredible, life-changing innovations of past years. But very little is known about them, with everyday Australians often unaware that these inventions are homegrown. Now you can follow their journeys! With thanks to Engineers Australia for this wonderful initiative.

Zaha Hadid Architects and ETH Zurich develop knitted concrete system








A double-curved concrete shell made with a 3D-knitted formwork in a collaboration between Zaha Hadid Architects and ETH Zurich has gone on display in Mexico City.

KnitCret is a new 3D-knitted textile system for creating curving concrete structures, without the need for expensive and time-consuming moulds.

The colourful pavilion is called KnitCandela in homage to the work of Spanish-Mexican architect and engineer Félix Candela, who created dramatic curved concrete shells in his buildings such as the Los Manantiales Restaurant in 1958.

Over two miles of yarn was knitted into four strips of between 15 and 26 metres in just 36 hours using a digital fabrication technique, then flown over from Switzerland to Mexico in suitcases.

World’s longest sea crossing bridge opens in China








The Hongkong-Zhuhai-Macoa bridge is now officially open. The bridge is 55-km long. It consists of a 22.9-km main bridge and a 6.7-km underground tunnel.  Surface area of the bridge is 700,000 square meters. It’s about the size of 98 standard football fields. Its main girders are made up of 420,000 tons of steel plates. The weight is equal to about 60 Eiffel Towers. It has the world’s longest immersed tube highway tunnel. The rubes reach a depth of up to 40 meters underwater. The bridge is curved as its piers are placed in the direction of water flow.

Car-free, more livable cities








Car-free, more livable cities

Here are 3 cities that have banned cars with amazing results.

  • Ljubljana, Slovenia – The streets in this city are filled with chatting pedestrians rather than traffic. If you live in the centre, you must park in a garage outside the car-free area. And if you’re elderly, disabled or a mother with children, you get free rides in electric taxis. Business and tourism have increased since the ban more than 10 years ago.
  • Pontevedra, Spain – This city banned cars 19 years ago. 70% of trips in the town are now on foot. And because the town is more livable, 12,000 people have moved into the centre. And air pollution has decreased by 61% since 2013.
  • Copenhagen – This city has over 96,000 square metres of car-free space. Two thirds of people commute by bike. And from 2019, it plans to ban new diesel cars to make its air even cleaner.

Our cities here in Australia should adapt this wonderful initiative. What do you reckon?

Water pipe turbines generating clean energy








American cities are putting turbines in water pipes to generate clean energy with zero environmental impact. In Portland, water mainly comes from the surrounding mountains. Gravity forces the water down the pipes, spinning the turbines and creating a source of clean energy under the ground. Because gravity is the force that moves the water, no extra energy needs to be used. Riverside, California is also installing turbines in water pipes. They generate enough energy during the day to power the water system itself and at night the turbines keep the street lights on.

Portland has installed turbines in 15 metres of pipes as a trial at a cost of 1.7 million dollars. They generate around 1,100 megawatt-hours of electricity every year. Enough to power about 150 homes and cut back on the use of polluting fossil fuels.

Should Australian cities install turbines in its water pipes too?
