    Hangzhou bridge bonanza
    By Daniel Allen







    BEIJING - China's Hangzhou Bay Bridge Bay Bridge, at 35 kilometers the world's longest trans-oceanic bridge, is having a wide-reaching impact on the economy of northeastern Zhejiang province and the seaport city of Ningbo to the south of the Yangtze River Delta.

    Opened in May 2008, the 12 billion yuan (US$1.75 billion) bridge is a showcase of Chinese ingenuity and technological prowess. Built to withstand extreme natural forces, the serpentine structure connects the cities of Jiaxing and Ningbo.

    "The opening of the bridge has meant that the vaunted 'two-hour circle' of the Yangtze River Delta region has finally become a reality," said Patrick Tong, secretary general of the Foreign Expert Committee of the Ningbo Chamber of International Commerce. "The bridge is not only convenient for tourists, but is also a vital link between booming provinces in one of China's most dynamic economic zones. It is triggering a restructuring of the whole economic landscape."

    Andrea Bernardi, who lectures in organization studies at Nottingham University Ningbo's Business School said "China's 'Golden Industrial Triangle' - a region bordered by Shanghai, Hangzhou and Ningbo - is really booming right now. The bridge has given Ningbo and companies operating in the area a key competitive advantage."

    Slashing the road distance between Ningbo and Shanghai from around 310 km to 180 km, and driving time from around four hours to 2ฝ hours, the Hangzhou Bay Bridge has clearly improved Ningbo's strategic standing. "We have definitely secured more business in the delta since the bridge opened," said Wang Wei, of Rockwood International Freight, a logistics service provider based in Hong Kong and Ningbo. “It's far more attractive for our clients to accept shipments out of Shanghai because of the savings in time and money."

    The bridge has also boosted foreign direct investment, said Wang Biao, chief economist of Camellia Universal, a Ningbo-based business consultancy. "Foreign companies attracted to Ningbo now include the likes of BP, HSBC, Samsung, Coca-Cola, Citibank, Allianz, UPS, Maersk Line, GM, Mitsubishi, Hitachi and Dupont."

    Tong said that at the Ningbo end of the bridge, "the counties of Cixi and Yuyao are now in prime positions. In Cixi, the Hangzhou Bay New Zone - which now covers 35 square kilometers - is still undergoing further expansion. Up until 2009, there were already 254 industrial projects established in the HBNZ, and more companies are setting up operations every month."

    One major beneficiary of Ningbo's logistical development is the city's extensive port area. The deepest seaport in China, Ningbo Port can handle vessels up to 300,000 tonnes, and cargo throughput is second only to Shanghai. Ningbo Port Company, the operator of Ningbo port, listed on the Shanghai Stock Exchange last year, and will go public in Hong Kong soon to raise further capital for ongoing development and expansion. A new line from the port to India and Pakistan opened in January this year.

    In 2006, to maintain competition with Shanghai's expanding Yangshan Port, Ningbo Port merged operations with a port on the nearby island of Zhoushan. The long-term objective is to increase container throughput from 10.93 million twenty-foot equivalent units (TEUs) in 2008 to 30 million TEUs by 2020. Despite lingering effects of the recent economic downturn, the port posted a container throughput of 966,100 TEUs in January 2010, a near 20% year-on-year increase. Continuing the upward trend, cargo and container throughput both reached a historical monthly high in January 2011.

    To underpin growth in imports and exports, a number of logistics parks, free trade and industrial zones have already been set up or are in the pipeline around Ningbo Port. The long-established Ningbo Economic and Technical Development Zone, from where an expressway leads straight to the Hangzhou Bay Bridge, is attracting investment from overseas.

    The Hangzhou Bay Bridge has also had a positive impact on Ningbo's tourism industry.

    "Many more Shanghai residents are taking one-day or two-day tours in Ningbo now," said Ye Xingfa, Marketing Director of the Ningbo Tourism Organization. "Last year, the number of international tourists visiting Ningbo was about 800,000, and the number of domestic tourists was around 40 million. This year we hope these figures will grow to around 1 million about 45 million respectively, and the bridge is certainly a major factor in this increase."

    Increased tourist numbers are having a knock-on effect on investment.

    "We've seen new hotels from Shangri-La, Marriott, Sheraton, and Sofitel recently," said Ye. "Investors in Ningbo's tourist infrastructure include private companies such as the Songcheng and Nanyuan Groups, and the local government, which has upgraded attractions such as the Tianyi Pavilion Library, Hemudu Culture Site Museum and Xi Kou Scenic Area."

    Having completed the Hangzhou Bay Bridge, Zhejiang continues to invest heavily in transport infrastructure to underpin economic growth. Last year, ground was broken on five high-speed railways connecting Nanjing and Hangzhou, Hangzhou and Ningbo, Shanghai and Hangzhou, Hangzhou and Changsha, and Jinhua and Wenzhou. According to a newly released 10-year urban plan for the province, three cross-sea railways will also soon be constructed, connecting Ningbo with Zhoushan, Wenzhou with Dongtou County, and Ningbo with Shanghai via another new bridge across Hangzhou Bay. The latter will shorten the railway link between Shanghai and Ningbo by more than 300 kilometers.

    "Every time I cross the Hangzhou Bay Bridge I think of a similar structure - the Oresund Bridge - which links Denmark and Sweden," said Bernardi. "Since Oresund opened in 2000, the Danes and Swedes have experienced ever deeper and more productive ties. With continued investment, Ningbo and neighboring areas will undoubtedly experience the same effect, albeit with 'Chinese characteristics', of course."

    Re: Hangzhou bridge

    It only took 150 years but the Middle Kingdom is finally catching up with another Kingdom. Wonder if "Made in China" will still be in service in another century and a half?

    A small selection of the works of Isambard Kingdom Brunel, one of the greatest engineers that ever lived [I have been over every one of these structures, which in their day were every bit as significant an achievement as the sometimes spectacular things we build today]:

    1. The Clifton Suspension Bridge over the Avon Gorge at Bristol, U.K. [Completed 1864]



    2. The Royal Albert Bridge over the River Tamar at Plymouth, U.K. [Completed 1859]




    3. The Windsor Railway Bridge across the River Thames at Windsor & Eton, U.K. [Completed in 1849, and today the oldest wrought iron bridge still in service]




    4. The Wharncliffe Viaduct across the Brent Valley near Hanwell, U.K. [Completed in 1837 and also still in use today]




    5. The Maidenhead Railway Bridge across the River Thames between Maidenhead, Berkshire and Taplow, Buckinghamshire, U.K. [Completed 1838, and at the time the widest arch span in the world. Yes, still in use today...carries 4 tracks of the high speed railway line west of Paddington, London]

      The last is by far the most impressive, a nine layer brick arch. Nothing more than a wooden former built strong enough to stand the weight of the brickwork while those nine layers were placed in situ, and then taken away. A simple labouring job by highly skilled brick layers. A work of art.

          There is a story that Brunel's employer, the Great Western Railway, expected the flat, elliptical arch [instead of the conventional semi-circular arch known since Roman times] to collapse under load and insisted that the wooden formwork be retained. Apparently Brunel went through the appearance of complying with the order by lowering the formworks slightly so it provided no structural support.

          Back in 2002 the BBC ran a series of programs to find "The Greatest Briton". Jeremy Clarkson hosted the program presenting the case for that title to go to fellow engineer Isambard Kingdom Brunel. But Churchill won that war too...

            Brunel was a man of many talents - he also designed ships like the Great Western and Great Eastern.

              Now you mention it, we should also give much credit to the woodworkers who will have constructed such a fine form with nothing more than saws, chisels and planes while using their mark one eyeballs. And also remember, no one had ever built anything like it before; so they were flying completely blind. Wonderful work.

                Brunel's SS Great Britain, a trans-Atlantic luxury liner launched in 1843, is preserved at a dry dock museum in Bristol, U.K.

                  What about the aqueduct of Segovia - built in the 1st Century AD

                  The aqueduct transports waters from Fuente Fría river, situated in the nearby mountains, some 17 kilometers (10.6 miles) from the city in a region known as La Acebeda. It runs another 15 kilometers (9.3 miles) before arriving in the city. The water is first gathered in a tank known as El Caserón (or Big House), and is then led through a channel to a second tower known as the Casa de Aguas (or Waterhouse). There it is naturally decanted and sand settles out before the water continues its route. Next the water travels 728 meters (0.45 miles) on a one-percent grade until it is high upon the Postigo, a rocky outcropping on which the old city center, the Segovia Alcázar, was built. Then, at Plaza de Díaz Sanz (Díaz Sanz Square), the structure makes an abrupt turn and heads toward Plaza Azoguejo (Azoguejo Square). It is there the monument begins to display its full splendor. At its tallest, the aqueduct reaches a height of 28.5 meters (93.5 ft), including nearly 6 meters (19.7 ft) of foundation. There are both single and double arches supported by pillars. From the point the aqueduct enters the city until it reaches Plaza de Díaz Sanz, it boasts 75 single arches and 44 double arches (or 88 arches when counted individually), followed by four single arches, totalling 167 arches in all.
