Chinese engineers have completed the world's longest desert freeway. Measuring 930 kilometers in length and costing 37 billion yuan (US$5.5 billion), the freeway extends from Linhe in the Inner Mongolia Autonomous Region to Baigeda on the border of Inner Mongolia and Gansu Province. The four-lane freeway runs through the Gobi Desert and the Badain Jaran Desert. It is part of the 2,582-km Beijing-Xinjiang freeway. By the end of 2016, China had 131,000 km of freeways in operation, more than any other country.
