At 41 kilometers long, the expressway connects Panzhihua in Sichuan province and Dali in neighboring Yunnan province. It opened to traffic last year, and is an important tourist corridor between Sichuan and Yunnan to promote the interconnection between the two provinces and facilitate economic development along the route.
