This massive infrastructure system transfers water from southern rivers to water-scarce northern regions, including Beijing. New canals, tunnels, and pumping stations were completed to improve water security. The project helps support agriculture, industry, and urban populations facing shortages. It is one of the largest water engineering efforts in history. While complex and controversial, the project shows China’s willingness to invest heavily in long-term resource management. It highlights how megaprojects can address environmental challenges alongside economic needs.

6. FAST Radio Telescope

Completed in 2016, the Five-hundred-meter Aperture Spherical Telescope, known as FAST, is the world’s largest single-dish radio telescope. Located in Guizhou province, this scientific megaproject allows researchers to study deep space signals and search for pulsars. The telescope’s enormous dish sits within a natural depression, reducing construction challenges. FAST has strengthened China’s role in global scientific research and astronomy. It also attracts international collaboration. This project shows that China’s megaproject ambitions extend beyond transportation and into advanced scientific research, demonstrating its commitment to technological leadership and innovation.

7. Beijing Zhangjiakou High Speed Railway

Completed before the 2022 Winter Olympics, the Beijing Zhangjiakou high-speed railway became the world’s first autonomous high-speed rail line. The railway connects Beijing with the Olympic venues in Zhangjiakou in about one hour. Smart systems allow trains to operate with high levels of automation. The project improved winter sports tourism and regional connectivity. It also demonstrated China’s progress in intelligent transportation technology. This railway played a key role in supporting Olympic logistics. The success of this project highlights how China integrates sports infrastructure with long-term transportation planning for lasting economic and social benefits.

8. Baihetan Hydropower Station

Fully operational in 2022, the Baihetan Hydropower Station is one of the largest hydroelectric dams in the world. Located on the Jinsha River, it has a generating capacity second only to the Three Gorges Dam. The project provides clean electricity to millions of homes and supports China’s renewable energy transition. Engineers used advanced dam construction techniques to manage the massive scale. The station also plays a role in flood control and water management. Baihetan demonstrates China’s continued investment in renewable energy megaprojects as it works to balance energy demand with environmental sustainability goals.

9. Shenzhen Bao’an International Airport Terminal 3 Expansion

Shenzhen continued expanding its airport infrastructure to support its fast-growing technology economy. Terminal expansions completed in the last decade added capacity and improved passenger experience. The airport features futuristic architecture and efficient transport connections.
