A ceremony has been held to commence construction of the Hangzhou Bay cross-sea railway bridge, the world's longest cross-sea high-speed railway bridge, in East China's Zhejiang Province.
A key section of the Nantong-Ningbo high-speed railway, the Hangzhou Bay cross-sea bridge was surveyed by China Railway Major Bridge Reconnaissance & Design Institute Co., Ltd., and will be built by China Railway Major Bridge Engineering Group Co., Ltd., both subsidiaries of China Railway Group Limited.
With a total length of 29.158 kilometers, the bridge includes a 450-meter main span cable-stayed section, a 2×448-meter main span cable-stayed section and a third section consisting of a cable-stayed 364-meter main span from north to south, and will span over three main channels.
The Nantong-Ningbo high-speed railway is a key part of the "eight vertical and eight horizontal" high-speed railway network in China and a crucial intercity link between city clusters of the Yangtze River Delta region.
Once operational, it is expected to shorten travel time between the major cities of the core area of the Yangtze River Delta region, optimize high-speed railway network in the region and improve the country's transportation network. It will also play a role in boosting the region's high-quality integrated development and contribute to the complementary advantages of regional resources and comprehensive and coordinated development.
