In news that brings to light the ever-worsening vehicle pollution and congestion problem in China, the 62-mile traffic jam near Beijing that officials say could last until mid-September has entered into its 10th day.

Local authorities have dispatched hundreds of police to try and maintain order and to reroute cars and trucks carrying essential supplies, such as food or flammables, around the main bottleneck. Vehicles were inching along little more than a third of a mile a day.

Zhang Minghai, director of Zhangjiakou city’s Traffic Management Bureau general office, said that he didn’t expect the situation to return to normal until around Sept. 17 when road construction is scheduled to be finished and traffic lanes will open up.
