    World's longest sea bridge spans 42.5-km over Jiaozhou Bay

    As if rising from the clouds, the world's longest sea bridge, the latest marvel of modern Chinese engineering, opened for traffic on Thursday.

    The 42.5-km span stretches across the wide blue waters of Jiaozhou Bay and connects the booming northern port city of Qingdao with an airport built on a nearby island and the industrial suburb of Huangdao. The first motorists to roll on to the Y-shaped bridge's sixlane, 33.5-metre-wide highway halved their journey time to the other side of the bay to just 30 minutes.

    Built in four years at a cost reported by the Chinese state media as $2.2 billion, the bridge stands on 5,200 pillars and was designed entirely by Chinese engineers at the Shandong Gausu Group.

    At least 10,000 workers toiled in two teams around the clock to build the bridge, working from opposite sides of the bay and linking the two ends together in the middle.

    While they were working on the bridge, more engineers were simultaneously building an accompanying tunnel underneath the bay, which will help to ease the traffic flow.

    A total of 450,000 tons of steel was used in the construction - enough for almost 65 Eiffel Towers - and 2.3 million cubic metres of concrete.

    Chinese officials said that the bridge would be strong enough to withstand a magnitude 8 earthquake, typhoons or the impact of a 300,000-ton ship.

    The bridge has eclipsed the previous world record span, the Lake Pontchartrain Causeway in Louisiana, by at least four km. However, it will be eclipsed in 2016 by another Chinese trestle bridge, which will linking Hong Kong with Macau and Guangdong province and will be about 50 km long.

    Photo gallery: China's Beijing-Shanghai bullet train


    China's 'bullet train' between Beijing and Shanghai is now running – or should we say, rocketing – along a high-speed railway stretching some 1,318 kilometres between the two cites. Christened 'Harmony', after the "harmonious society" slogan of Chinese President Hu, the sleek train completes the journey in under five hours.


    Business class carriages feature airline-inspired touches like reclining seats with in-seat entertainment systems, and are staffed by uniformed 'stewardesses' serving Chinese delicacies. The cost? $260 (1,750 Yuan).

    And you can forget about a smoking carriage: the entire train carries a novel no-smoking policy for this nicotine-addicted nation, which results in some passengers stepping out at any of the 24 stations along the route for a fast one-minute puff.

    The service runs from the new Beijing South station – just off the south second ring road and with its own station on Beijing's subway line 4 – to Shanghai's new Hongqiao station, with connections to lines 2, 5 and 10 of the Shanghai Metro.

    Several changes were made to the train in the months before its official launch.The top speed has been reduced to 300km/h from the previously-promised 380km/h due to concerns over both safety and cost. Authorities also dropped plans for a series of luxury 'VIP' carriages in order to keep overall ticket prices down, opting for a simpler set of two-class carriages.

    The daily schedule feature three services. The fastest and most expensive has have only one stop along the way, at Nanjing.
    A second service stops at seven provincial capital cities for a total travel time of five and a half hours.The 'slowest' train stops at all 24 stations along the route, travelling at 250km/h instead of 300km/h, but comes with cheaper fares than the super-express service.

    The 220.9 billion yuan (A$32 billion) line will be the longest and most expensive high-speed rail connection in the world, and will carry an estimated 160 million passengers a year.

    World's longest gas pipeline operates in China


    BEIJING - China's second east-west natural gas pipeline went into operation on Thursday.

    The pipeline, connecting central Asia and China, will send natural gas from Turkmenistan to South China's Pearl River Delta after passing through 15 of the country's provinces.

    The pipeline is the world's longest, with a total length of 8,700 km. The pipeline was built with 142.2 billion yuan ($21.98 billion) in investments.

    There were talks about Indian railways looking into the feasibility about staring their own high-speed trains, but looking at he fares of the Chinese bullet trains, around 260 dollars, I wonder what the fares would be if India launches such high-speed trains running at 250-300 kms.

    nope.i think this shows indian officers r cautious about such a huge project.

    china has stopped the high-speed train project emergencily.

    we found some problems such as wether it is needed all over the country.

    the investment on it is too big.

    but for us people,high-speed is a good thing.for example,now from my city to beijing now costs just 21min.while it costs 2 hours more before

    1. there are three levels of tickets and most tickets cost 450-700 RMB.

    2. not all the CRH project are stopped, the project under construction are still in the process. only the project are considered less important are stopped, the important ones will go on

    It seems you did not read through the news article that the link points to ! It states that the ticket prices run up to 260 USD. That's about 1700 RMB, or equivalent to INR 11000 ! That's freaking costly for Indian standards.

    building a sea bridge and a tunnel to link the place is just a waste of money. i am really wondering how the hell could both projects got approved by the authority. do they have brains?

    More than the purpose, it has to do with show of engineering and economical might to the outside world.

    That RMB 1750 (USD260) is for so-called luxury class, while the cheapest fare for 'economy class' is at RMB 410 (USD63) quite affordable for Beijing-Shanghai. But meanwhile it's reported that some airline has discounted to as low as RMB 360 subj to tax (68% off normal price) in face of keen competition (good for travellers anyway).

    I'm happy as often shuttling on HSR. That cuts my trip from previous 4hrs averagely by Bus to 110mins. HSR is clean and cozy with pretty stewardess. But unlike Beijing-Shanghai bullets my route tops at 250kmph only.
