What is the amount of new bridges built in Germany and China? What is the ratio? 1:300? 1:500? Something along those lines I guess.

Newly-built bridges simply do not collapse in countries like Germany or France or Canada or Japan or... due to high construction standards, but also better technical oversight/inspection.

Both of which are woefully lacking in China, past or present.

The main problem is they transport coal, sand and gravel in trucks that are over 20 meters long, and if loaded to capacity (what usually happens) they can weigh over 100 tonnes. The recently collapsed bridge in Harbin had three such trucks on the collapsed segment. Which means these trucks have weighed close to 300 - 350 tonnes combined, on a single segment. This is the same as 300 -350 passenger cars.

Furthermore, these trucks may not have been the only factor, if there is sustained usage of overweight trucks on bridges like these, they can wear out very fast, and will collapse at some point. In other words, with sustained overweight usage, these bridges age tremendously fast until the point they collapse even if they were designed to handle higher loads.

If I understand correctly this bridge serves a new development of Harbin with large-scale construction, and that is likely where the sand/gravel trucks came from.

What's the last time you see trucks that's 300-400% overload drive onto bridges clearly not designed for that kind of load?

Even the Chinese themselves are questioning the quality of construction and the frequency of bridges collapsing.

Quote:
Collapsed bridges have become worryingly frequent in China. Earlier this month, a bridge collapsed in Guangchang county in Jiangxi Province, killing two and injuring two. Another incident this month in Dalian, Liaoning Province killed six, according to the Xinhua News Agency.

"As China experienced a decade of fast-speed construction, it has entered a dangerous period since corruption in public infrastructure projects is becoming an open secret," Zhu Lijia, a professor at the Chinese Academy of Governance, told the Global Times.

If you load a truck with an 18 * 2.5 * 3 = 135 m³ capacity with sand, the load alone weighs approximately 200 tons. Add the weight of the truck to it (approximately 15 tons) and you have a truck weighing 215 tons.

The regular limit in Europe is mostly 40 tons, while most bridges are capable of up to 60 - 70 tons per truck if it's not sustained usage of trucks with such weight. (chiefly exceptional transports)

Then there is another problem. Lack of signage regarding weight limitation and the enforcement of such regulations.

Quality takes time, when a country is industrializing they don't have the money and time to make the quality top notch. When South Korea was industrializing, it too had some incidents, so China is not so different when considering its size too.

In 1994 in Seoul, South Korea, a big bridge collapsed, due to weak construtction.



In 1995 in the same city, a whole department store collapsed also due to weak construtction.

At the same time they also acknowledged that illegally overloaded trucks is a major contributing factor the bridge collapse. http://www.chinadaily.com.cn/cndy/20...t_13006216.htm
Having seen some of those trucks I'm surprised this few bridges collapse every year. There are always clear signage posted on bridges but illegally overloaded trucks always choose to ignore them.

Note that Shanxi and Shaanxi are two separate subdivisions of China.
The second one is the S45 Tianli expressway. I know because the section North of the recently opened one (From G5/G20 to Yu county) is in Google Maps. I believe ultimately it will run from G7 near Tianzhen (On the very short section G7 will have in Shanxi) to G18 in Licheng. The other "unknown" one is also unknown to me.

And both 山西 and 陕西 are transliterated to Shanxi. But the second one has to be longer due to the tone, so is translated to Shaanxi.

Edit: Scrap this, I though the second expressway ran from Yangquan instead of Yushe. It has to be a Sxy, where y is an even number.

China Approves Plan to Build New Roads to Boost Economy
Bloomberg
Sep 7, 2012 12:00 AM GMT+0800

China approved plans to build 2,018 kilometers (1,254 miles) of roads, its second major construction project announced this week, as the government boosts spending on infrastructure to help revive economic growth.


The projects include highways in Zhejiang and Xinjiang provinces, according to statements on the National Development & Reform Commission’s website. The approvals were given during June-August period. The agency also cleared plans for nine sewage treatment, two waterway and five port and warehouse projects, without disclosing the required investments.

The announcements came a day after the NDRC, the country’s top economic planner, backed plans for subway projects in 18 cities and after an increase in the rail-construction budget as the government tackles growth that has eased to the slowest pace in three years. The move will help accelerate infrastructure investment growth to more than 20 percent year-on-year from 15 percent, according to HSBC Holdings Plc.

“Beijing policy makers are stepping up efforts to speed infrastructure investment to hold up growth,” Qu Hongbin and Sun Junwei, economists at HSBC, said in a note yesterday. “We expect a fast filtering-through process to generate a modest growth recovery in the coming months.”

The approvals on Sept. 5 for a total of 25 new subway and inter-city rail projects are worth more than 800 billion yuan ($126 billion), or 1.7 percent of 2011 gross domestic product, they said. The spending will run from the second half of the year to 2018.

Shares Surge

Shares of rail builders and trainmakers surged yesterday after the rail announcement. CSR Corp Ltd. (601766), China’s biggest trainmaker by market value, surged 8.8 percent, the most in almost nine months, to close at HK$5.20 in Hong Kong trading. China Railway Group Ltd. (601390) and China Railway Construction Corp, the nation’s two biggest rail and metro line builders, both jumped more than 6 percent. The benchmark Hang Seng Index rose 0.3 percent.

“We believe most of the projects were already in local governments’ plans and the approvals may accelerate the development,” said Citigroup Inc. analysts Jenny Zhen and Paul Gong in a note to clients yesterday. “This sentiment is positive for the whole railway construction and equipment sector.”

Among the approvals, Shanghai got the go-ahead for an expansion of previously approved metro line projects. About 16.8 billion yuan of new spending, including a 4.4 billion-yuan line extension to the planned Disney theme park, was added to an existing plan.

The Chinese government also recently boosted plans for 2012 spending on railway construction to 496 billion yuan, according to China Railway Group. It is at least the third increase since the start of July when Premier Wen Jiabao said promoting investment growth is key to stabilizing economic expansion.

China Economy

China’s economy, the world’s second-biggest, expanded 7.6 percent in the second quarter from a year earlier, the slowest pace in three years. Manufacturing slowed in August, according to surveys of purchasing managers, with one gauge at the lowest level since March 2009.

Premier Wen has pledged policy “fine tuning” to cope with a deepening slowdown as export gains slump to an annual 1 percent pace in July from 11 percent in June. The deterioration in trade escalated the risk that Wen will miss his full-year economic expansion target for the first time since he took office in 2003.

“It seems to reflect that the economic data in the second half won’t be great,” said Vivian Liu, a Shanghai-based analyst with Sinopac Securities Asia Ltd. “The government has to rely on increased fixed asset investment to help economic growth.”

I've read they were studying two possible routes for G6 between Huanyang (West of Xining) to Golmud. They were G109 and the Qingzang railway, so probably they chose the later one and shortened G3011, Liuge expressway, to the G215/G315 cross.

Uhm, let's see...

After at look at Chinese Wiki, I found it's numbered S4 according to it's name, Chengzilu expressway. The name suggests it will be extended to G76 Xiarong expressway at Luzhou.
