On April 13th, the prefabrication of box girders for the Shandong section of the national key project Jinan Zhengzhou high-speed railway was completed, and the Shandong section of the Jinan Zhengzhou high-speed railway entered the stage of comprehensive synchronous box girder erection and track laying. The Jizheng high-speed railway is an important component of the national "eight vertical and eight horizontal" high-speed railway network. After the project is opened, the travel time from Jinan to Zhengzhou will be reduced to 1.5 hours, becoming a fast passenger transportation channel between the Central Plains urban agglomeration and the Shandong Peninsula urban agglomeration.
