Mega bridge for high-speed railway completes closure in Shandong

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.

Tokyo stocks tumbled on Tuesday, with the benchmark Nikkei index falling below the 70,000 mark after snapping an eight-session winning streak, as investors took profits amid concerns over an overheated market.

The 225-issue Nikkei Stock Average ended down 2,565.58 points, or 3.55 percent, from Monday at 69,788.38.

The broader Topix index, meanwhile, finished 104.67 points, or 2.56 percent, lower at 3,990.38.

On the top-tier Prime Market, nonferrous metal, electric appliance, and information and communication issues were notable decliners.

The Nikkei briefly traded higher at the open but soon reversed course as selling pressure mounted after the index had surged more than 8,100 points during its eight-session advance.

Heavyweight technology shares, particularly recent gainers such as Kioxia Holdings Corp. and Tokyo Electron, led the decline. The selloff was partly cushioned as dip-buyers stepped in.

Losses extended in the afternoon, with the Nikkei diving more than 3 percent toward the close.
