川藏公路历来号称死亡线,而这死亡线上最难闯的亡命段——就是黑昌公路了。黑昌公路全程764公里,由西藏那曲(原名黑河镇)往东,经索县、巴青、丁青、类乌齐,到达昌都,于1960年在原有的驿道基础上修通。该线对于沟通那曲东三县(巴青、索县、比如)、开发林区、以及加强那曲和昌都地区经济联系等方面都有重 Sichuan-Tibet Highway has always been known as the death line, and death line of the most inaccessible death - that is, the Black Chang Road. The entire stretch of Hei Chang Highway is 764 kilometers long. It runs east of Hequ, Tibet (formerly Heihe) and reaches the Qamdo via Suoxian, Baqing, Dingqing and Wuqi. In 1960, it was built on the basis of the original post road. The line has important implications for the communication of the Naqu three counties (Paqin, Suoxian, for example), the development of forest areas, and the strengthening of economic links between Nagqu and the Chamdo areas
