In August 2010, a staggering 12-day traffic jam occurred on the Beijing-Tibet Expressway, affecting over 100 kilometers of road. The gridlock began on August 14 due to a combination of road construction and heavy vehicle traffic, particularly trucks carrying coal and construction materials from Mongolia to Beijing. The expressway was partially closed for roadwork, creating an unprecedented bottleneck as vehicles became immobilized. Authorities responded by halting traffic on alternate roads to expedite the clearing process, prioritizing stranded trucks to gradually restore movement. The jam was finally cleared on August 26, 2010, after extensive efforts by traffic management teams. During this period, local vendors capitalized on the situation, setting up makeshift stalls along the roadsides to sell snacks and cold drinks at inflated prices. Additionally, many drivers and passengers formed temporary settlements, adapting to the harsh conditions of being stuck in traffic for days. This historic incident underscored the critical need for robust infrastructure and effective traffic management strategies to prevent similar situations in the future.
