initial traffic jam was solved, poor road conditions still persisted for years. And in August of 2010, one of the longest traffic jams ever recorded started that lasted for roughly 10+ days. Trucks carrying supplies to help road construction and ease congestion around the city were one of the main causes for the traffic jam. There were roughly 100,000 travelers that ended up stuck in the traffic jam. Throughout the whole traffic jam vendors came to sell food and water to drivers/passengers as they waited for the whole ordeal to be over Potential trouble spots: Guanting service area Toll gates (on the expressway, not at the individual exits) Major checkpoint at Kangzhuang, Beijing At the toll station in Daijiaying, and at every exit in the Beijing direction, road signs urged drivers to use China National Highway 110 instead of the Jingzhang Expressway. The traffic jam meant that traffic that would take two hours to travel from Zhangjiakou to Beijing now took nearly two days. These traffic jams continued on and off well into 2005. As a result, a second expressway linking Beijing to Zhangjiakou is in the plans. Reason for the jams: bureaucracy. At every change of jurisdiction, there was a toll gate where lorries not only paid their tolls but also underwent weight examinations. Trouble was, every province had different standards and did not recognise the certificates issued from toll gates in other provinces claiming that the lorries were not overloaded. Beijing enforced a very low tolerance and forced even passenger cars to undergo the weight examination. If a lorry was overweight, it had to unload and pass through the test again. Few people cooperated, instead willing to sit it out by parking their lorries on the hard shoulder of the expressway. The average time it took for a lorry to get through the test varied: 5 – 50 minutes, depending on the results. Road conditions Speed limit Most of the expressway has a speed limit of 110 km/h. Hillier terrain has a lower speed limit of 80 km/h. The Guanting Bridge has a maximum speed limit of 80 km/h. Speed checks are rare. Tolls Entire stretch charges tolls. Toll system not networked. Lanes 4 lanes (2 up, 2 down) throughout. Surface conditions Moderately good. Traffic Traffic conditions to Zhangjiakou from Beijing: Very good. Traffic conditions to Beijing from Zhangjiakou: Good. Major exits Donghuayuan, Huailai, Jimingyi, Xiahuayuan, Zhangjiakou. Service
