The world's longest traffic jam took place in Bejing, China, that started to form on August 14, 2010, mostly on China National Highway G110 and Beijing–Tibet expressway G6, in Hebei and Inner Mongolia. The traffic jam slowed down thousands of vehicles for more than 60 miles and lasted for more than 11 days. Several drivers were able to move their transport only 1 km per day, and some drivers being stuck in the traffic jam for five days. It is believed to be one of the longest traffic jams.
The cause of the traffic jam was a spike in traffic by heavy trucks heading to Beijing, along with National Highway 110's maintenance work that began five days later. The road construction which reduced the road capacity by 50% contributed heavily to the traffic and minor breakdowns and accidents were compounding the problem. You can imagine how would it be difficult to get the foods, and the locals near the highway sold numerous goods like water, instant noodles, and cigarettes at exaggerated prices to the stranded drivers. Even a bottle of water normally cost 1 yuan, but on the highway it was sold for 10 yuan.
