Science Discussion Forum / Some highest International Bridge............
« on: November 27, 2012, 10:59:57 PM »
1. Siduhe River Bridge. Yesanguanzhen, Hubei, China.

Description: 1,627 feet high / 496 meters high
2,952 foot span / 900 meter span.

With a roadway 1,627 feet (496 mtrs) above the water, the Siduhe River bridge is the latest Chinese champ to take the record as the highest bridge in the world. Opened on November 15th, 2009, it is the 3rd Chinese bridge in less than a decade to claim the title of “World’s Highest Bridge” and is a symbol of just how fast and how far China’s highway infrastructure has come in such a short period of time.

Located about 50 miles (80 km) south of the famous 3 Gorges region of the Yangtze River in China’s mountainous Hubei Province, the Siduhe suspension bridge is just one of several amazing structures on the last 300 mile (483 km) link of the 1,350 mile (2,175 km) long West Hurong highway that now connects Shanghai on the Pacific coast with the cities of Chongqing and Chengdu in the west.

The 8 highest of China’s many high bridges were all built after 2000 and are located primarily in the 3 western Provinces of Guizhou, Hubei and Chongqing. All 8 of these bridges exceed 900 feet (274 meters) in height and rank among the world’s 12 highest while four have held the world record for highest road or rail bridge. Even more amazing, 6 of these bridges are higher than Colorado’s Royal Gorge, the former world’s highest bridge from 1929 to 2001.

2. Baluarte Bridge. El Palmito, Sinaloa, Mexico
Description: 1,321 feet high / 403 meters high
1,706 foot span / 520 meter span

The Baluarte River Bridge is not only the highest bridge in North America but the highest cable stayed bridge in the world surpassing the Millau Viaduct in France. It is the crown jewel of the greatest bridge and tunnel highway project ever undertaken in North America. Known as the Durango-Mazatlán highway, it will be the only crossing for more than 500 miles (800 km) between the pacific coast and the interior of Mexico. The path of this new highway roughly parallels the famous “Devil’s Backbone”, a narrow road that earned its nickname from the way it follows the precarious ridge crest of the jagged peaks of the Sierra Madre Occidental mountains. The dangerous road is a seemingly endless onslaught of twisting, terrifying turns that are so tight there are times the road nearly spirals back into itself.

Description: 532 feet high / 162 meters high
940 foot span / 287 meter span

Réunion Island is a French territory located east of Madagascar Island in the Indian Ocean. Just 35 miles (56 kms) across, the region has become a popular tourist getaway as well as a permanent home to more than 800,000 residents.

Travel between the many coastal communities on Réunion Island has always been through a network of older, two lane roads that traverse in and around many deep rifts cut from rain runoff tumbling down the tall volcanic peaks that created the island. To relieve congestion on the west side, it was decided to build a 30 mile (50 km) north-south highway called the Route des Tamarins. Crossing dozens of huge ravines, the new route required the construction of 3 tunnels, 9 interchanges and 4 major bridges including the Saint Paul, the Trois Bassins and the Ravine Fontaine viaducts. The longest and highest crossing of all is the one over Grande Ravine.

Dropping almost vertical for much of its 532 foot (162 mtr) depth, the Grande Ravine site is perfect for a frame bridge. The design chosen by the engineers is a sleek, stealthy looking span with a 940 foot (286.5 mtr) long span box girder resting on two angled struts of just 20 degrees - an incline so shallow they almost look as level as the road deck! The concrete struts are part of a cantilever that is counterweighted on the back sides by two large abutments filled with tons of soil. Like many strut frame bridges that are hard to categorize among bridge types, Grande Ravine is especially complex with an arch effect only occurring under service loads. To construct the main span without using wind prone towers and a high line, the famous French bridge company Freyssinet designed a unique stay cable system to support the two half decks as they were launched out from either side of the canyon.

Miracle Fruit (Synsepalum dulcificum)

The miracle fruit, or sweet berries, is a very strange berry native to West Africa. What makes the fruit strange and miraculous, is miraculin (a sugar substitute), which is found in large quantities in the fruit, combined with a glycoprotein. The fruit itself does not contain a lot of sugar, and tastes only mildly sweet but when eaten, the glycoprotein binds to the tongues taste buds, which, for about an hour after eating the fruit, distorts any other taste into sweetness. With that effect you could technically eat a lemon, and it would taste like a ball of syrup. Although the definite reason for this occurrence is not fully understood, it would seem as if the miraculin distorts the shape of the sweetness receptors in the tongue so that they pick up on acid instead of sweetness. The sweetness receptors on your tongue then transmit to the brain to taste sweetness when they come in contact with any acidity. In the 70s attempts were made to commercialize and sell the fruit as a diet aid, as it has the potential to turn any meal sweet, without affecting your calorie intake. These attempts were shattered when the FDA declared it a food additive, due to pressure from sugar companies who could foresee big losses in profits. In the last two years the berries have been making a comeback, by being the guest star of many tasting parties in the states. The berries are dried and exported, and the party guests each have one and then taste all kinds of common foods to experience a new taste sensation with every bite.

Bael (Aegle marmelos)

Bael, wood apple or stone apple is a species native to India, but found throughout Southeast Asia. Bael is a smooth fruit with a woody peel that is colored yellow, green or grey. The hard, woody, outer peel is so hard that it has to be cracked with a hammer. Inside is an aromatic yellow pulp with several hairy seeds. The flesh can be eaten either dried or fresh. From the fresh fruit, a juice called sharbat can be made, adding water, sugar and lime juice to the pulp. It takes just one large fruit to make 6 liters of sharbat.

Duku or lungsat are two very similar fruits found throughout Asia. They come from the same family, look and taste identical, with one difference. The skin of the lungsat contains a latex substance, which is not poisonous, but causes the skin to stick slightly to the fruit, whereas the duku has no latex and the peel is removed with more ease. Inside, the fruit has 5 segments, some of which has bitter seeds inside. It is a very sweet fruit and can be prepared in a number of different ways, including being canned in syrup or being dried like raisins.

Salmonberry (Rubus spectabilis)

Salmonberrys are native to the west coast of North America, stretching from midway through Alaska, all the way down to California. They are found in moist forests and create dense thickets. The fruit looks similar to raspberries, but are more orange in color. They are sweet when eaten raw, but are often processed into juice, wine, candies and jams.
