I've been in nasty traffic jams, but nothing like one near Beijing:

As the jam on the highway, also known as National Highway 110, passed the 10-day mark Tuesday, local authorities dispatched hundreds of police to keep order and to reroute cars and trucks carrying essential supplies, such as food or flammables, around the main bottleneck. There, 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 in a telephone interview 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.

I guess China doesn't do anything small...
