What is the difference between bridges and viaducts?
The difference lies in their primary use, position and construction. A viaduct usually refers to long bridges or series of bridges connected to one another by arch bridge structures that carries a road or a railway across a valley or a gorge. Bridges, on the other hand, are usually built over bodies of water.
How were viaducts built?
Roman engineers called them viaducts, and the first ones were built in a similar way to the aqueducts that the Romans made famous. Viaducts usually consist of a series of multiple bridges connected by a series of arch structures or spans between tall towers made of stone, concrete, iron, or steel.
What are the achievements of the Chinese highway construction industry?
The most striking achievement in highway construction has been the road system built on the cold and high Qinghai-Tibetan plateau.
Is high-speed rail a boon or Bane to China’s economy?
Five years after the busiest bullet trains started running (the Beijing-Shanghai line opened in 2011), a tentative verdict is possible. In the densest parts of China, high-speed rail has been a boon: it is helping to create a deeply connected economy.
How does China’s Railway system work?
The central government operates a major rail network in the Northeast built on a base constructed by the Russians and Japanese during the decades before 1949 and an additional large system inside (that is, to the south or east of) the Great Wall. The framework for the railways inside the wall consists of several north-south and east-west lines.
What is the history of high-speed rail in China?
In addition, upgrades to track and equipment have facilitated high-speed passenger rail service between Beijing and Shanghai, Guangzhou, and Harbin. The first modern highway in China was built in 1913 in Hunan province.
