The railway is expected to reduce the journey time from Ningbo to Suzhou and Shanghai to around one hour.^[2]

In October 2020, geological surveys began in preparation for the construction of a bridge across Hangzhou Bay which will carry the railway.^[3]

Construction on the railway started on 30 November 2022.^[4]

The line takes new north–south route which bypasses Shanghai, instead heading via Suzhou, Jiaxing, and Cixi. The total length of the line is 310 kilometres (190 mi), of which 301 kilometres (187 mi) will be newly built. The line crosses the Yangtze River via two tracks of the four-track Hutong Yangtze River Bridge. The other two tracks carry the Nantong–Shanghai railway.

It is however not the first railway to travel between Suzhou and Jiaxing. The Suzhou–Jiaxing railway operated from the 1930s to 1944.
