QINGDAO -- The Qiangkuang Reservoir Mega Bridge, part of the connection line of the Weifang-Suqian High Speed Railway to Qingdao City in east China's Shandong Province, completed closure on Tuesday, marking a milestone for the project.

Located in Wulian County in Shandong, the mega bridge features a concrete continuous beam with a total length of 621.7 meters, a width of 24.6 meters, and a total weight of more than 100,000 tons.

As the only over-water ultra-wide, multi-span, long-span continuous beam bridge along the route, the mega bridge is designed with four tracks on the same beam to serve as a core corridor for both the main Weifang–Suqian high-speed railway and the Qingdao connection line.

The connection line is a key link between the Second Beijing–Shanghai High-Speed Railway and the coastal corridor of the country's "Eight Vertical and Eight Horizontal" high-speed railway network.

Upon completion, the project will greatly facilitate travel between the Jiaodong Peninsula and regions to the south, promoting the integrated development of the Jiaodong Economic Circle, the Beijing-Tianjin-Hebei region, and the Yangtze River Delta.
