Expressways drive China into a prosperous future (4)

A section of a bridge for the Simao-Lancang Expressway in Southwest China's Yunnan province is seen on Jan 20, 2021. The expressway shortens travel time between the two ends of the expressway from 3.5 hours to 1.5 hours. Its operation is expected to boost joint economic development in Puer's downtown and in the triangle-shaped region consisting of Lancang, Menglian and Ximeng counties. In addition, the expressway will link the Kunming-Bangkok Expressway, the Lancang-Mekong "international golden waterway", and Lancang Jingmai Airport, which will promote opening-up of the border areas.
