Apparently folks felt dissatisfied with the results of the first jam, and have decided that a "do-over" would fix things.
"BEIJING – Thousands of coal trucks and other vehicles were backed up for miles on a highway in northern China on Friday, the latest in a series of monster traffic jams that have plagued the overloaded road since construction began on a parallel route earlier this summer.
Police redirected traffic and reminded drivers to stay alert in the gridlock along on the Beijing-Tibet highway, an official with the Jining district traffic police in Inner Mongolia said Friday. Like many Chinese bureaucrats, he refused to give his name."
