Just yesterday (Jan 16, 2026), the Hangzhou Bay Cross-Sea High-Speed Rail Bridge marked a major engineering milestone as its first main tower was successfully topped out. Stretching 29.2 km across the water 🌊, it currently holds the title of the world's longest high-speed railway cross-sea bridge under construction.
Designed for speeds up to 350 km/h 🚄, this giga-structure blends cutting-edge tech with bold design. Topping out the main tower signals that key vertical work is complete, bringing us one giant leap closer to the bridge’s grand opening in 2027.
Once finished, the bridge will supercharge connectivity across the Yangtze River Delta, slashing travel times and fostering high-quality, integrated development in the region.
More than a transport link, this bridge symbolizes how bold infrastructure can drive progress and unite communities. Keep an eye on this record-breaking marvel as it transforms travel in 2027! 🌟
