#5. Drivers in China Got Stuck in a Traffic Jam for 12 Days
It happened in 2010, when someone got the bright idea to do some construction work along a stretch of the busy Beijing-Zhangjiakou highway, ostensibly for the purpose of making the constant traffic problems suck less. Instead, they managed to accomplish the exact opposite. Apparently, no one foresaw that when you take an already seriously overtaxed highway and close half the lanes, everything stops. Traffic slowed to the infuriating, grandpa-like speed of 1 kilometer (a bit over half a mile) per day. The 75 miles of highway essentially turned into a big parking lot. Oh, and it was summer.
