People are diligent and spring comes early; the year begins with a "flying start." Before the festive atmosphere of the 2024 Spring Festival had faded, work on the Haizhu Bay Tunnel Project—invested in and built by Guangzhou Communications Investment Group and constructed by China Railway 14th Bureau—was already in full swing.
To ensure construction progress, during the Spring Festival more than 200 management personnel and workers stayed on site, seizing the dry-season construction window of the holiday without stopping work, and completing the demolition and reconstruction of the north half of the Sanjiao Interchange section of the Ring Expressway in 12 days with a "fast, steady and precise" approach.

On February 18, at the launch shaft construction site, the two super-large-diameter shield machines on the east and west lines—"Avenue Pioneer" and "Pathbreaker Pioneer"—had fully resumed tunnel boring operations after comprehensive maintenance, with management personnel and over a hundred workers all back on duty. Accompanied by the hum of the shield machines, processes such as box culvert loading and unloading, segment assembly, shield advancement surveying, and slurry treatment were carried out in an orderly manner, presenting a busy scene on site.

Regarding the critical period of the Spring Festival dry season and post-holiday resumption of work, according to Zhang Min, the project's safety director, after the holiday the project held a "first lesson of work" and carried out the "seven ones" for resuming work and production, safeguarding the safe and efficient advancement of the project.
Beating the drum to urge the march, striving high and comparing strength. Up to now, the Haizhu Bay Tunnel shield has successfully passed beneath the friction pile group of the China Nuclear Business Building, the Sanzhixiang Waterway, and the dense residential houses at the Luoxi Island fault zone, successfully overcoming three major risk construction points. The west-line "Avenue Pioneer" shield machine has completed 68% of its boring, and the east-line "Pathbreaker Pioneer" shield machine has completed 71%; the dual-line shields are now passing beneath the Rear Channel of the Pearl River and are about to break through the 1,500-meter mark, with breakthrough expected in July this year.

It is reported that the Haizhu Bay Tunnel Project has a total investment of 11.68 billion yuan and is the northern section of the Guangzhou South Station Express Corridor. As a key construction project of Guangdong Province and the city, it has been included in the "Guangdong Provincial Expressway Network Plan (2020–2035)." The project route is 4.35 kilometers long with a maximum excavation diameter of 15.07 meters, making it Guangzhou's first super-large-diameter shield tunnel; it is expected to be completed and opened to traffic in June 2025. Once completed, the project will form a rapid corridor between the city center and Guangzhou South Station, potentially shortening the drive from Guangzhou's central urban area to Guangzhou South Station to 15 minutes, strongly enhancing the station's collection and distribution capacity and promoting connectivity within the Guangdong-Hong Kong-Macao Greater Bay Area.
