Life and Growing Bridge

The bridge is one of the infrastructure to facilitate the engineering of human transportation. Built bridges at the location on the river, valley, or the sea that separates it. But somewhere in this world, the bridges that connect the rivers were not built, but alive and growing!


1. Root Bridge in India

In the depths of south-eastern India, in one of the wettest locations on earth, the bridges are made in a very strange and unique.

Grow from the roots of rubber trees, the people using Khasis in Cherrapunjee nut tree, split it and took it to make what is called "pointer roots". When spread and reach the other side of the river, they began to integrate with the roots from the soil. Over time, the bridge is sturdy and life began to take shape.


Root bridges that some anatarnya reach 30 meters, takes 10 to 15 years to be able to function fully, and make it very sturdy. Some can take the weight up to 50 people at once.



One of the most unique structures in Cherrapunjee known as "Double-Decker Umshiang Root Bridge." Consists of two layers of the bridge, above and below.



Because these bridges are still alive and continues to grow, making it more robust. Some of the old bridge root has been used every day by people around the village Cherrapunjee since more than 500 years ago.


2. Bridge vines in Iya Valley, Japan


One of the three valleys of "hidden", in Japan, West Iya is the place foggy canyon, the river clean, and the roofs of straw or leaves, as described Japan centuries ago. To cross the river that flows Iya along the slopes of the valley, the robbers, the kstria, and refugees to make a special bridge made of vines.


Below is a picture of a bridge of vines in 1880:

First, the two plants Wisteria - one of the most robust vines - planted for very long from both sides of river. When the plant reaches a sufficient length, and then woven together with the board to make a living botanical engineering, soft but very sturdy.



The bridges had no sides, and a source of Japanese history shows that the bridge is unstable plants, and who tried to cross the first time are often frozen in place, unable to continue any further.


Three of the bridges were still in the valley Yes. Although some (not all) the bridges were reinforced with wire and the sides of the lanes, it is still scary to cross. Longer than 42 meters, with a board that is placed every 6 to 8 inches, and the fact that one fell into the water from a 4.5 story, making it suitable for people with acrophobia (fear of heights).


Some people believe the bridges vines there were first built in the 12th century, which makes some of the examples of architecture in the world's oldest living.




3. Root Bridge in West Sumatra

Here he's flagship tourist attraction of South Coastal District which is one of the most unique bridges in the strong and dunia.jembatan a liaison between the two regions Jorong (Hamlet) and Puluik-Lubuak Puluik glare, glare Lubuak Village, North Bayang Sub-district, South Coastal, West Sumatra.


From the information summarized one of the successful community leaders and youth chairman Pulik-puluik, Herman Bandaro Datuak Rajo, the bridge was made because of a scholar named Pakih Sokan sorry to see students Pulik-mengajinya from puluik often do not come because the flow is often swollen stem shadows .


In the year 1916 Pohan Pakih planted two sticks ox-ox (a type of banyan tree broad-leaf), tree-ox ox is planted in two locations one in Pulik-puluik area and one in the glare Lubuak stem separated by shadows. Then the roots are dangling in woven bamboo rod made of bone bridge as the root bridge. After 3 years the roots of two trees-ox ox is linked but not impassable.

Then Pakih Pohan mandabiah held goat (goat) and mandarai aka (giving blood at the root of that link). "This is a sign of thankfulness that ox-ox roots connected already linked, as a sign of convergence will happen again," added Herman.


To make a bridge impassable takes over 20 years so the bridge can be taken Puluik-puluik citizens who want to want to Lubuak glare.


Until now the bridge measuring 30 meters long and 1 meter wide with a height from the surface of the shadow rod about 10 feet and at the age of the bridge is already 93 years and still can be passed from the local residents Pulik-puluik as many as 25 heads of families as well as citizens who want to kedaerah Pulik-puluik.

Millau Viaduct "The world Biggest Bridge"

This bridge is the "Millau Viaduct" which was built in the French country in order to reduce the congestion in the city.

Privileges "Millau Viaduct"

Millau Viaduct from the center of attention at the International since December 2004 inaugurated ago. The bridge, designed by British architect, Norman Foster, stands firmly above the Tarn River and connects massive mountain range. This project is run by the French construction company, Eiffage. This steel bridge is done simultaneously from two sides of the valley, south and north. The merger of the steel plate into parts that connect the seven pillars is repeated up to 18 times!! No wonder that his construction project took three years of this highly anticipated crowds.
Viaduct PanjangMillau reached 2.46 km to the seven pillars each sectionnya buffer. The lowest altitude of the pillar is the pillar 77 meters while the highest reaches 343 meters. 23 meters taller than the Eiffel Tower Bo!! When viewed from a distance, the seven pillars of support like a giant needle stuck into the valley based strong. This bridge was so high, no less cloud in the area just under the bridge! Khan proved wuihh reply .. we can walk, even driving above the clouds?? tupac ...

We put the first stone of this bridge construction, development of Transport Minister of France, Jean-Claude GAyscot stated that this bridge will be the largest and highest bridge and the most beautiful in the world. And the result ... Millau Viaduct has 3 straight world record!

World Records Millau Viaduct

Some title 'highest' successfully achieved, including:

The highest pylons in the world
Previous world record held by Kochertal bridge over the road (Germany) is as high as 181 meters (590 feet). But the Millau Viaduct is breaking records, with pylons (P2 and P3) as high as 244, 96 meters (about 803 feet) and 221.05 meters (about 725 feet) in height respectively.

Highest in the world pole
With the highest pole (P2 dipuncak) as high as 343 meters (about 1130 feet), of course, became the world's tallest mast today. Something about this record would have emulous not ya??

Bridge deck in the world's highest road
Above the Tarn River with the highest dititik 270 meters (890 feet), Millau Viaduct is almost two times higher ordinary bridges. Slightly higher than the New River George Bridge in West Virginia, USA, wrote as high as 267 meters (880 feet).

No less than 394 million Euro being poured for the manufacture of the bridge width and thickness of 32.05 meters road is 4.20. So, not one reply charging the government for every rider yg past. Set fares ranging from 4.6 euros (6.5 euros in the summer) for a small vehicle, up to 19 Euro for a big car. Just info, this bridge could hold 10,000 to 25,000 vehicles in a single path lho bgt .. amazing ...

Extreme Engineering : A bridge across the Bering Strait

The concept of an overland connection crossing the Bering Strait goes back at least a century. The route would lie just south of the Arctic Circle, subject to long, dark winters and extreme weather (average winter lows −20°C with possible lows approaching −50°C.). Winter maintenance of any exposed roadway would be difficult and closures frequent. Even maintenance of enclosed roadways and pipelines could also be affected by winter weather.

According to Discovery Channel the Bering Strait could be spanned by a series of three bridges via the Diomede Islands for a total distance of about 80 km (50 miles). The two long spans would be comparable in length to the Lake Pontchartrain Causeway, the current longest bridge.

Ice breakup after each winter is violent and would destroy normal bridge piers, so the 55-mile-long bridge would need 220 piers, cone-shaped to resemble and function like the bow of an icebreaker ship, and weighing 50,000 tons each. The bridge would require thousands of kilometers of new road and/or track over extremely harsh terrain through the wilderness of Alaska and Siberia.

The bridge as envisioned would be three stories: the top for vehicle traffic, the middle for high-speed trains, and the bottom for oil and gas pipelines. The top would be open to cars and trucks only during summer months.

Discovery Channel's Extreme Engineering estimates the cost of a highway, double track rail and pipelines, including continuations on land, at $105 billion. This excludes the cost of new roads and railways to reach the bridge. There have been long discussions about a highway for the benefit of residents in western Alaska, but environmental concerns and fears of undue cultural influence from a higher number of visitors to Eskimo villages have obstructed these plans.

The scary damaged extreme bridge

Want your heart pounding Left Through Bridge? If you want to try just a little challenge through the Bridge Under the Bridge is:
