 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 G50 Shanghai-Chongqing West Hurong Expressway 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 1,300 feet (400 meters) in height and dominate the world’s 10 highest while four have held the world record for highest road or rail bridge.  Even more amazing, 50 Chinese bridges are now higher than Colorado’s Royal Gorge, the former world’s highest bridge from 1929 to 2001.

-It would only be appropriate that the second highest suspension bridge in the world is also on one of the greatest bridge “high-ways” in the world.  Stretching 300 miles (483 km) from Yichang and the 3 Gorges dam in the east to the city of Zhongxian in the west, this 4-lane engineering marvel has more than half a dozen spectacular bridges that exceed 500 feet (150 meters) in height including Zhijinghe, formerly the highest roadway arch bridge in the world.  This more direct route bypasses one of the toughest and most mountainous stretches of the Yangtze River.  What once took more than a day of travel on dangerous mountain roads or a Yangtze river boat can now be safely traversed in 5 hours.

 The success of the route also owes as much to the construction of the numerous tunnels that punch through dozens of towering peaks that blocked the highway’s path.  One of the more impressive of these tunnels leads to the east end of the Siduhe bridge and makes for one of the world’s more dramatic bridge introductions.
-With a span of 2,952 feet (900 mtrs), Siduhe bridge is a fairly typical long span Chinese suspension bridge with H-frame concrete towers, a truss stiffened road deck and unsuspended side spans.  One aspect of its construction that was not so ordinary relates to its extreme height.  Due to the remote, inaccessible river canyon, the engineers decided to experiment and instead of using a blimp or helicopter to drag the first pilot line across the gorge, they would use a rocket.  Over 3,281 feet (1000 meter) of tether was attached to the back end of a 4 foot (1.5 mtr) long rocket and blasted across the deep river gorge.  Also unusual is the termination of the east end bridge cables into a long tunnel foundation deep under the steep slope of the mountain.

 The Warren truss has a depth of 6.5 meters and a width of 26 meters.  Each truss section measures 6.4 meters.  The entire structure is supported by concrete towers 113.6 and 118.2 meters tall.

 Siduhe translates to Four Crossings River.  “Si” means four while “du” means crossings and “he” means river.  The name probably came from the Red Army’s famous Four Crossings of the Chishui River in Guizhou Province during Chairman Mao Tse Tung’s Long March in 1935.
-A trip along the G50 expressway to Siduhe bridge is a truly spectacular experience as you will be treated to an assortment of huge bridges of every size and variety.  West of Siduhe there is the Zhijinghe bridge, the world’s highest roadway arch that soars 965 feet (294 meters) above the river gorge.  East of the bridge there is the incredible parade of 200 meter high monsters including the Tieluoping cable stayed bridge, the Shuanghekou beam bridge and finally the Longtanhe viaduct - a multi span concrete beam bridge that is one of the world’s 10 largest and highest beam bridge viaduct.  (France’s Millau is still the world’s highest viaduct overall).

 Siduhe is so high that its closest foreign rival in Mexico is over 100 meters lower.  It is 672 feet (205 meters) higher than Colorado’s Royal Gorge bridge.  The structure also has the unique distinction of being the first bridge in the world where a person falling from the deck can reach terminal velocity - the speed at which a falling object will no longer accelerate.  With so many unprecedented superlatives, the Siduhe River bridge retained its world's highest suspension bridge status for 16 years before it was surpassed in 2025 by the Beipanjiang Huajiang Bridge in Guizhou Province.

 在国道主干线系统之外，还有进一步国家高等级公路网的建设，包括七个独立的干线，称为“7918”。7是指的以北京为中心向外辐射的数条独立线路，至于其他的数字是指，9条南北线、18条东西线。这些较短的公路线的很多条都将用来联系人口超过20万的城市。目前这一系统仍然还有25000英里（40000公里）多的部分没有建成，在未来的2020年完全建成之后，将会有很多高桥存在的公路值得期待。如果中国的经济在2020年之后仍然持续增长，届时将会有另外的56000英里（9000公里）的高等级公路可能会建设，把全国的总公路里程数提高到109000英里（175000公里）这些高等级公路都设有收费站。如果你想了解更多关于中国的高速发展的公路网的建设，去维基百科看看中国高速公路的主页看看吧：
