各地一批重大工程建设迎来关键节点

CCTV.com (Xinwen Lianbo): A number of major construction projects across the country are now reaching key milestones, laying a stronger foundation for high-quality economic and social development.

Today, October 22, in Wuhu, Anhui, conductor stringing began for the major Yangtze River crossing of the Gansu–Zhejiang ±800-kilovolt ultra-high-voltage direct-current transmission project, a key project in the west-to-east power transmission initiative. The entire Anhui section is expected to be connected before the end of the month. The Gansu–Zhejiang ±800-kilovolt ultra-high-voltage direct-current transmission project passes through six provinces and has a total length of about 2,370 kilometers. Once operational, it will transmit 36 billion kilowatt-hours of electricity annually, more than half of which will be green electricity.

Transport infrastructure construction is accelerating. The north navigation channel bridge of the Hangzhou Bay Cross-Sea Railway Bridge recently achieved closure. The Hangzhou Bay Cross-Sea Railway Bridge is a key project controlling progress on the Nantong–Suzhou–Jiaxing–Ningbo high-speed railway. With a total length of 29.2 kilometers, it connects Jiaxing and Ningbo in Zhejiang and is currently the world's longest cluster-type cross-sea railway bridge under construction.

The first heavy-tonnage precast concrete box girder for the Dalian Changhai Bridge, China's largest mainland-to-island highway project under construction by investment, was recently successfully installed, marking the start of construction of the bridge's superstructure. The bridge has a total length of about 25.5 kilometers, including a sea-crossing section of about 19 kilometers, and is an important component of National Highway 507.

In Fuyuan, Heilongjiang, the main works of the Heixiazi Island highway port project were recently completed. Once put into use, the project will overcome the seasonal constraints of Fuyuan's existing ports and enable regular customs clearance throughout all four seasons of the year.

Water conservancy construction is making steady progress. On October 20, the cofferdam for the expanded riverbed excavation on the left bank of the Guangdong Huangmaoxia Reservoir complex project successfully achieved closure, bringing the project into the main construction phase within the river channel. The project is a landmark major water conservancy project under the national initiative for major national strategies and security capacity building in key areas. The Huangmaoxia Reservoir project has a designed total storage capacity of 570 million cubic meters and is expected to be completed and put into use in 2030, when it will further improve the flood control system in the middle and lower reaches of the Pearl River.
