East Sea Bridge begins at Luchao Port in Nanhui County of Shanghai, crosses over north area of Hangzhou Bay, passes through Dawugui Island, Kezhushan Island and finally lands Xiaoyangshan Port Area at Xiaochengzi Hill. The total bridge length is approximately 31km. The bridge carries dual 3 lanes plus emergency lanes. The free width of deck is 31.5m. The design speed is 80km/h with traffic design load automobile-20 and check load trailer-120. The traffic load of full-loaded container trucks with central distance of 10m is checked too. The design life of the bridge is 100 years and seismic design load is earthquake intensity 7 degrees.

According to the site locations, the bridge is composed of 3 major sections: shallow shoal section connecting new and old sea embankments in Luchao Port, oversea section connecting new sea embankment and Dawugui Island, and island section connecting Dawugui Island and Xiaochengzi Hill. The lengths of three sections are 2.3km, 25.5km and 3.2km respectively.

Except for two cable-stayed bridges, the superstructures are concrete continuous box girders. Each deck has identical cross-section with single cell box and cantilevers of 4m at each side.

In shallow shoal section, the superstructure is mainly composed of multi-span post-tensioned concrete box girders with constant height of 1.6m and length of 30m. The substructures are consist of Φ600mm PHC pipe piles, plate type pier shafts with widened pier top and reinforced concrete rectangular pile caps.

In oversea section, there are three bridge types: bridge over shallow water, non-navigational low level bridge, main and auxiliary navigational bridges.
The bridge over shallow water consists of totally 26 spans of post-tensioned concrete continuous box girders with constant height of 3.0m and length of 50m. The foundations are made of Φ1600mm bored piles.

The non-navigational low level bridge has totally 333 spans in length of 60m and 70m. The foundations are made of mainly Φ1500mm steel pipe piles. The superstructure is 3.5m high multi-span post-tensioned concrete continuous box girders converted from simple supporting erection.

There are three auxiliary navigational spans. One for 1000DWT navigation has span length of 80+140+140+80m and clearance of 25m, and two for 500DWT navigation have span lengths of 70+120+120+70m and 90+160+160+90m respectively and clearance of 17.5m.

The substructure is made of Φ2500mm bored piles and the superstructures are post-tensioned concrete continuous box girders with varied cross-sectional depth.

Over the main navigational span there is a double pylon single plane cable-stayed bridge with composite girders, 40m clearance and 73+132+420+132+73m spans (see Figure 2). The main piers are designed to resist 10,000DWT ship collision. The foundations are made of Φ2500mm bored piles of 120m long. The reinforced concrete pylons are 150m tall in inverted Y shape with varied cross-sections of pylon shafts. The main girder is steel concrete composite of single box with 3 cells.

The island section is consist of various types of structures, including hill-exploded roadcut, sea embankments and Kezhushan Bridge.

The hill-exploded roadcuts on Dawugui Island and Kezhushan Island are made of soft bitumen pavement and 3-steps grouted rubble slope.There are sea embankments connecting Dawugui Island and Kezhushan Island, which is enrockment slope. Kezhushan Bridge is a double pylons and double planes cable-stayed bridge with composite girder (see Figure 3). Total length of Kezhushan Bridge is 1.6km connecting Kezhushan Island and Xiaoyangshan Island. The span configuration of the cable stayed bridge is 50+139+332+139+50m. The foundations are made of Φ2500mm bored piles. The reinforced concrete pylons are 100m tall in H shape. The approaching bridges are multi-span post-tensioned concrete continuous girders with span length of 50m and height of 3.0m. The foundations adopt both Φ2500mm bored socketed piles and Φ1500mm steel pipe piles.

Oh my god!!! A bridge in Hangzhou Bay!!! I'm not too clear on the explanation but does this bridge just link a small island port in the middle of the bay to Shanghai or does it cross the ENTIRE Hangzhou Bay to another city? Also, in comparison to other long bridges, how long is this one?

article on it

China Builds World's Longest Trans-oceanic Bridge
After 10 years of preparations, construction on China's first trans-oceanic bridge will start Sunday at the Hangzhou Bay in east China. With an estimated price tag of 11.8 billion yuan (1.42 billion US dollars), the 36-km-long bridge will be the longest of its kind in the world.




PRINT DISCUSSION CHINESE SEND TO FRIEND






The World's Longest Trans-oceanic Bridge Begins Construction
--------------------------------------------------------------------------------
After 10 years of preparations, construction on China's first trans-oceanic bridge will start Sunday at the Hangzhou Bay in east China.

With an estimated price tag of 11.8 billion yuan (1.42 billion US dollars), the 36-km-long bridge will be the longest of its kind in the world.

The stayed-cable bridge, linking Cixi City on the southern bank of the bay with Jiaxing City on the northern bank, will be built in five years.

With a designed life span of 100 years, it will have six lanes in two directions, with a designed driving speed of 100 kilometers per hour.


The World's Longest Trans-oceanic Bridge Begins Constructuion(2)
--------------------------------------------------------------------------------
Upon completion, daily traffic volume on the bridge is estimated to reach 45,000 vehicles during its first year of operation.

The bridge will shorten the journey between Shanghai and Ningbo by 120 kilometres, making it a 179-kilometre journey, Zhejiang Governor Lu Zushan said Sunday. "It will certainly enable each part of the delta to develop much closer relations with one another, and greatly enhance the area's overall economic growth,'' said Lu.

Wang Yong, chief director of the Hangzhou Bay Trans-Oceanic Bridge Construction Command Post, said the bridge will be one of the most important not only in China but in the world "for it is not only the longest one (over a sea) but also will be built in the world's most complicated sea environment, with one of the three biggest tides on Earth, the effect of typhoons and the difficult content of the sea soil.''

That is why preparatory work started on the bridge as far back as 1994, said Wang. During the past nine years, more than 120 technical research projects have been carried out on the planning of the bridge, with the help of more than 700 experts from throughout the world.


China Begins Building World's Longest Trans-bay Bridge
--------------------------------------------------------------------------------
The construction project involves investment of over 11.8 billion yuan (US$1.4 billion), 35 percent or around 297 million yuan (US$36 million) of which has been raised by businesses in Zhejiang. Another 7 billion (US$846 million) or 59 percent was provided as loans from the State Development Bank of China, Industrial and Commercial Bank of China, China Bank and Shanghai Pudong Development Bank.

The Yangtze River Delta covers an area of 100,100 square kilometres and has a population of 135 million. It is regarded as the world's sixth-largest metropolitan area after London and Paris. It includes the 15 most prosperous cities in China as well as half of the country's 100 wealthiest counties.

Although the area has only 10.4 per cent of China's population, it accounted for 22.1 percent of the country's gross domestic products last year, 24.5 percent of the country's revenues and 28.5 percent of the country's import and export volume.

Governor Lu said: "It will be much easier for the area to jointly work on several grand projects, such as international tourism development, the building of world-class deep-sea ports, and so on.''

Recent schemes in the area include Shanghai's Yangshan deep-sea port, which involves investment of 12 billion yuan (US$1.45 billion) and is scheduled to be completed in 2005.

The development of Shanghai into an international shipping centre will also involve Ningbo, Zhoushan and Jiangsu Province's Taicang, which boast of some of the best deep channels in the country.

At the northern end of the Hangzhou Bay bridge, a new industrial zone is under construction in Jiaxing. It will cover an area of 25 square kilometres.

On the southern side, another new industrial zone with total investment of over 1.7 billion yuan (US$205 million) is also under construction.

Ningbo has become a new investment option for many transnational corporations in Shanghai. With more convenient transportation between the two, corporations are expected to be increasingly willing to invest in the city, where land prices are comparatively cheaper.

Another bridge is being built between the island city of Zhoushan and the mainland, costing 5.8 billion yuan (US$701 million).

Other large-scale projects being undertaken on both sides of Hangzhou Bay involve the chemical, steel and car industries.

"All these will surely combine to make a tremendous impact on the development of the whole delta area. A new era has arrived for the Yangtze River Delta,'' said Lu.

China's first self-designed and self-built bridge, the Qiantang River Bridge, about 200 km away from the new sea-crossing bridge, was completed in 1937. Up to now, China has constructed thousands of bridges on its rivers.

Construction of the new sea-crossing bridge is an indication of China's increasing economic power, and it is expected to boost economic development in the Yangtze River delta.

Following the Hangzhou Bay bridge, a number of sea-crossing bridges at the Bohai Bay, Huangdao in Shandong Province and East China Sea will be constructed involving more than 100 billion yuan(12.09 billion US dollars), authoritative sources have disclosed.

In the early 20th century, Dr. Sun Yat-sen, forerunner of the democratic revolution of China, had initiated the construction of a Hangzhou Bay trans-sea bridge.
