Sweeping across the Beijing skyline, the Jingxin Shangdi Bridge stands tall. It’s a modern marvel, also known as the Shangdi Bridge. This bridge isn’t just a way to get from point A to point B. It’s a symbol of engineering prowess. It also holds the title of Beijing’s tallest and longest bridge, a remarkable feat.
The Shangdi Bridge carries the Jingxin Expressway, part of Beijing’s Fifth to Sixth Ring Road. It gracefully spans multiple layers of transportation below. Imagine trains rushing beneath you on the Beijing Subway Line 13, the Jingbao Railway, and the Jingzhang Intercity Railway. The bridge also arches over city roads, creating a vital artery in Beijing’s bustling network.
Construction of the Shangdi Bridge began in May 2010. The main structure was completed in November 2011. The bridge officially opened to traffic on January 1, 2012, easing congestion on the Jingzang Expressway. The bridge’s design is a testament to innovative engineering. It’s a five-span continuous single-tower cable-stayed bridge made of prestressed concrete. The main bridge stretches 510 meters. The main span reaches an impressive 230 meters, with a side span of 198 meters. The bridge deck is 35.5 meters wide, and the main tower soars 99 meters high. The bridge’s foundations, or abutments, are massive, containing 12,000 cubic meters of concrete and reaching a thickness of 8 meters. The cable-stayed design features 44 pairs of 88 cables, with the longest cable measuring 222 meters and weighing a hefty 27 tons. The total weight of the cables is a staggering 1,411.8 tons.
Building this bridge was no easy task. The main tower was constructed using a liquid pressure climbing formwork technique. The bridge spans busy railway lines, including Beijing Subway Line 13. It intersects with Line 13 at a 15-degree angle. To avoid disrupting train service and overcome limited construction space, engineers employed an ingenious “cantilever pushing” method. This involved pushing a 212-meter-long, 25,000-ton section of the bridge into place across a distance of 213 meters. This was the largest cantilever pushing operation in China at the time. This innovative “two-point limited position” cantilever pushing method earned national recognition. It also received awards from the Ministry of Transport and the Beijing Municipal Engineering Design. The bridge also boasts the world record for several curved concrete box girder cantilever pushing construction parameters, including the heaviest bridge section (25,000 tons), the widest deck (35.5 meters), and the longest cantilever length (63 meters). The Shangdi Bridge earned the prestigious Zhan Tianyou Award. It also won at the 15th China Civil Engineering Zhantianyun Award.
The naming of the bridge also has its own story. On September 17, 2010, the Beijing Municipal Planning Commission announced the official name: Jingxin Shangdi Bridge. This name was approved by the Beijing Municipal People’s Government. The Shangdi Bridge isn’t just a structure of steel and concrete. It’s a symbol of connection, innovation, and progress, elegantly uniting different parts of Beijing.
