TRACES: YELLOW RIVER
New highway. Xian, Shaanxi, China 2011.
In 2011, China’s highway system became the longest in the world—longer than the United States, which had been the undisputed leader for at least 50 years.
In 1990, China produced 42,000 passenger cars. By 2004, the number hit one million, with 16 million cars on the nation’s roads. By 2000, motor vehicles were the leading cause of China’s urban air pollution and in 2010 it overtook the United States as the world’s largest market with the sale of 13.8 million new cars.
