There was once a traffic jam that lasted over a week in China.
In Aug. 13 2010, a traffic jam on National Highway 110 near Beijing kept cars stuck in traffic for 10 days. The traffic jam itself went on for 60 miles. On average, the trapped vehicles were stuck moving about â..." of a mile per DAY. Truck drivers in the jam kept themselves entertained by playing cards. Local vendors sold food to the unlucky motorists (mostly ramen at marked-up prices).
