Beijing (Fenzhongsi - Shibalidian - Dayangfang - Majuqiao - Caiyu) - Langfang (Hebei) - Tianjin (Yangcun - Central Tianjin - Tianjin Airport - Tanggu District/TEDA). History The expressway opened on September 25, 1993, and was the first express to be built to more recent standards. This expressway has slashed driving time from Beijing to Tianjin to around one hour, and has created a corridor between Beijing and Tianjin. Accidents Areas of the expressway are many times very foggy and that has led to a number of accidents. On October 19, 2004, seven vehicles involved in three accidents plunged into each other in early morning fog, killing two and injuring many more on the stretch of expressway from Beijing to Tianjin, at the stretch between Majuqiao and Caiyu. Parallel Expressways With a history of over ten years, the expressway was beginning to feel the crunch of massive traffic, especially the increase of heavy lorries. As a result, at least two other expressways linking Beijing to Tianjin were constructed. A variation of routes leaves Beijing heading toward Pinggu District, and links with the Jinji Expressway.
