The Guangzhou-Lianzhou Expressway in China, built by CCCC, was officially put into operation. Located in Guangdong Province, its 38-km-long second phase is a comprehensive project integrating bridges, roadbeds, tunnels, and interchanges. 
Led by innovation, CCCC applied the UAV intelligent patrol system for the first time in China's expressway construction. Also, while traveling along the route, you can enjoy the view of green mountains and lucid waters. Take a look!
