Giant Dragons of the Sea: A Magnificent Epic of China's Cross-Sea Bridges
China's cross-sea bridges, resembling giant dragons soaring over the sea, connect the mountains and rivers across the country and stand as testament to Chinas astounding achievements in bridge construction. These grand projects are not only the crystallization of modern technology but also a symbol of the wisdom and strength of the Chinese people.
I. Hong Kong-Zhuhai-Macau Bridge: Connecting Three Regions, Creating a Shared Future
The Hong Kong-Zhuhai-Macau Bridge, a super-large cross-sea passage connecting Hong Kong, Zhuhai, and Macau, stands as the world's longest cross-sea bridge with its unique "bridge-island-tunnel" design. With a total length of 55 kilometers, including 22.9 kilometers of bridge and 6.7 kilometers of underwater tunnel, it showcases China's extraordinary bridge construction capabilities.
The bridge portion consists of three navigable cable-stayed bridges and 20 kilometers of non-navigable bridges. The "Chinese knot" design of the Qingzhou Navigation Bridge symbolizes the close connection and shared development of the three regions. The completion of this bridge has not only significantly reduced travel time between Hong Kong, Zhuhai, and Macau but also facilitated personnel flow and economic exchanges between the three regions, injecting new vitality into the development of the Guangdong-Hong Kong-Macao Greater Bay Area.
II. Hangzhou Bay Bridge: Spanning the Bay, Connecting Development
The Hangzhou Bay Bridge, spanning the Hangzhou Bay in Zhejiang Province, connects Jiaxing and Ningbo cities. With a total length of 36 kilometers, it was once one of the longest cross-sea bridges in the world. Its completion has shortened the land distance between Ningbo and Shanghai by over 120 kilometers, providing crucial transportation infrastructure for the economic development of the Yangtze River Delta region and driving urban development and industrial upgrades along the route.
Faced with complex marine environments and harsh weather conditions, the builders employed innovative technologies like box girder prefabrication and construction, ensuring the stability and safety of the bridge. Traveling across the bridge offers breathtaking views of the vast Hangzhou Bay, showcasing the grandeur of nature and the prowess of human engineering.
III. Beipanjiang Bridge: Soaring Above the Clouds, Challenging Limits
The Beipanjiang Bridge, located at the junction of Yunnan and Guizhou provinces, is a super-large bridge on the Hangzhou-Ruili Expressway. With a height difference of 565.4 meters between the bridge deck and the river surface, it once held the record for the world's tallest bridge. The bridge's construction faced numerous challenges, including complex terrain and fragile geological conditions. The builders, with innovative design and construction techniques, successfully erected this giant bridge across the canyon.
The completion of Beipanjiang Bridge has significantly improved local transportation conditions, promoted economic development in the Yunnan-Guizhou region, and become a dazzling scenic spot, attracting countless tourists.
IV. Dan-Kun Bridge: High-Speed Railway, Racing Across Thousands of Miles
The Dan-Kun Bridge is a super-large railway bridge on the Beijing-Shanghai High-Speed Railway section from Danyang to Kunshan. With a total length of 164.851 kilometers, it is the world's longest bridge. It crosses numerous roads, rivers, and lakes, employing various bridge structures to provide a solid foundation for the smooth operation of the high-speed railway, showcasing China's powerful capabilities in railway bridge construction.
The completion of the Dan-Kun Bridge has not only shortened the distance between north and south but also promoted economic development along the route, providing strong support for China's economic takeoff.
V. Qingdao Sea Bay Bridge: Wings of the City, Soaring Over the Sea
The Qingdao Sea Bay Bridge, also known as the Jiaozhou Bay Bridge, is located in Qingdao City, Shandong Province. With a total length of 36.48 kilometers, it is a super-large cross-sea bridge independently designed, constructed, and built by China. The bridge boasts an elegant design, with its unique double-tower cable-stayed bridge design for the main bridge becoming a dazzling landmark in the city of Qingdao.
The completion of the Qingdao Sea Bay Bridge has strengthened connectivity between Qingdao and surrounding areas, promoting economic development and urban construction in Qingdao, and providing a new channel for transportation in coastal regions.
VI. Pingtan Strait Bridge: Bridge of the Strait, Connecting the Future
The Pingtan Strait Road-Rail Bridge, located in Fuzhou City, Fujian Province, spans the Pingtan Strait. It is China's first road-rail cross-sea bridge. The bridge's location, with high winds, waves, and strong currents, made construction extremely challenging. However, the builders overcame numerous difficulties and successfully completed the bridge.
The completion of the Pingtan Strait Road-Rail Bridge has not only significantly improved transportation conditions in Pingtan but also accumulated valuable experience for Chinas bridge construction in complex maritime environments. This experience lays a solid foundation for the future construction of larger cross-sea bridges.
VII. Sidu River Bridge: Hanging High Above the Canyon, Challenging Precipices
The Sidu River Bridge, located in Enshi Prefecture, Hubei Province, is a suspension bridge. The bridge deck is 560 meters above the valley floor, making it once the world's tallest suspension bridge. During construction, the builders innovatively employed rocket-launched guiding cables, solving the problem of guiding cable laying and setting a precedent in bridge construction history.
The completion of the Sidu River Bridge is of great significance for improving local transportation and promoting economic development. It also demonstrates the courage and wisdom of China's bridge builders.
VIII. Aizhai Bridge: Soaring Over the Canyon, Connecting Dreams
The Aizhai Bridge, located in Jishou City, Xiangxi Prefecture, Hunan Province, spans the Dehang Grand Canyon with a main span of 1176 meters. This bridge is not only a transportation hub but also a beautiful scenic spot. The construction of Aizhai Bridge has played an important role in promoting tourism development and economic prosperity in the Xiangxi region.
IX. Guozigou Bridge: At the Foot of the Tianshan Mountains, Connecting the Future
The Guozigou Bridge, located in Yili Kazakh Autonomous Prefecture, Xinjiang Uygur Autonomous Region, crosses through the Guozigou Canyon. The bridge has elegant lines and blends seamlessly with the surrounding natural scenery. Its completion has improved local transportation conditions, brought new opportunities for economic development and tourism in Xinjiang, and set a new benchmark for transportation construction in Xinjiang.
X. Balinhe Bridge: Spanning Mountains and Rivers, Connecting Hope
The Balinhe Bridge, located at the junction of Guanling County, Anshun City, Guizhou Province, and the Huangguoshu Scenic Area, is a large-span steel truss suspension bridge with a main span of 1088 meters, a total length of 2237 meters, and a height difference of 370 meters between the bridge deck and the Balinhe River surface. The construction employed numerous advanced technologies, including mobile tower cranes and temperature control of large-scale anchor blocks, ensuring the quality and progress of the project.
The completion of the Balinhe Bridge is of great significance for promoting transportation development in the Guizhou region and coordinating regional economic development. It significantly shortens the travel time between the Huangguoshu Scenic Area and Guanling County, strengthens connection and communication between the two places, and provides strong transportation support for the development of Guizhou's tourism industry, making it easier for more tourists to enjoy the beautiful scenery of Guizhou.
