This must just be great for the environment: A 62-mile-long traffic jam has punished Beijing drivers for nine days, highlighting China’s worsening car congestion. A surge of traffic from heavy trucks August 14 first slowed traffic on the Beijing-Tibet expressway, and then roadwork made it worse five days later. The clog is so bad that local merchants have begun selling water and food to trapped drivers at high prices. The highway has been plagued by heavy traffic as it’s a key artery bringing goods, groceries, and coal into the city from Hebei and Inner Mongolia. The slowdown is expected to last till mid-September.
