Engineering Marvel Connects Regions Amid Infrastructure Push
In a landmark achievement for modern engineering, the Daxihe Grand Bridge achieved full structural closure on February 4, 2026, after four years of meticulous construction. Spanning 1,662 meters across challenging terrain, this double-tower cable-stayed structure features a record-breaking 650-meter main span – the world's longest for bridges using double-edge I-shaped composite girders.
The bridge forms the centerpiece of the new Fengjian Expressway, a critical infrastructure project designed to enhance regional connectivity and economic integration. Engineers overcame complex geological conditions through innovative composite material applications and precision construction techniques.
"This project demonstrates China's leadership in large-scale infrastructure development," said lead architect Wang Li during the connection ceremony. "The design optimizes both structural integrity and environmental sustainability, setting new standards for future transportation projects."
Strategic Economic Implications
The completion comes as Asian nations accelerate cross-border infrastructure initiatives. Analysts predict the expressway will reduce logistics costs by 18% along its route when fully operational this year, potentially reshaping regional supply chains.
With its advanced monitoring systems and earthquake-resistant design, the Daxihe Bridge represents a significant leap in smart infrastructure development. Transportation officials confirm the expressway will open to commercial traffic by Q4 2026, connecting major industrial hubs across three provinces.
