The longest traffic jam on record happened on China National Highway 110, starting on August 14, 2010. The traffic jam slowed thousands of vehicles for more than 60 miles (100 km) and lasted for 12 days. Traffic at that time moved 0.6 miles per day.
Occurring on China National Highway 110, many drivers were stuck in traffic for days, running out of fuel, food, and water. It resulted in a microeconomy, with area residents taking advantage of a rare opportunity for an unsurpassed market.
Five years later, in October 2015, the 50-lane G4 Beijing-Hong Kong-Macau Expressway was tied up for over 10 days, due to a checkpoint put in place as 750 million people traveled during a holiday marking the establishment of the People’s Republic of China in 1949.
