April 2026, the Guangdong Provincial Public Resources Trading Platform officially issued a tender announcement for the special consultation service for the pre-relocation of the Zhuhai-Maoming section of the Shenzhen-Nanning Expressway, the West Extension Line of the Shenzhen-Zhuhai Passage. This marks that the trans-provincial high-speed artery with a total investment of about 84.4 billion yuan and a total length of 358.84 kilometers has officially entered the substantive early stage, and related work is expected to start in June, with a centralized construction period from 2026 to 2032. At the same time, the planning of the composite rail-cum-road corridor of the Shenzhen-Zhuhai Passage (Lingdingyang Passage) has been carried out simultaneously, and the two super projects have been implemented in coordination, which has become the core and most certain demand-driven engine of the Guangdong-Hong Kong-Macao Greater Bay Area cement market.
The Shenzhen-Zhuhai Passage is a highway-railway composite sea-crossing passage, including a two-way eight-lane expressway, a high-speed rail with a speed of 350 km/H and an inter-city railway with a speed of 200 km/H. It crosses the Lingdingyang Sea and has strict requirements on the performance of cement. The Zhumao section of Shennan Expressway starts from Zhuhai High-tech Zone, passes through Zhongshan, Jiangmen, Yangjiang and Maoming, and ends at the boundary between Guangdong and Guangxi. The proportion of bridges and tunnels along the whole line is high, and the interchange hub is dense. The roadbed, bridges and culverts, tunnels and ancillary works are the focus of cement consumption.
According to preliminary calculation, the total consumption of the two projects will exceed 10 million tons of cement, and the demand structure will be significantly upgraded. The proportion of high-grade road cement, sulfate-resistant and chloride-resistant marine special cement has been greatly increased, which is more suitable for cross-sea, heavy-duty and long-life engineering standards. This demand covers Zhuhai, Zhongshan, Jiangmen, Yangjiang, Maoming and other cities along the western Guangdong line, and radiates the eastern part of Guangxi, effectively driving the regional cement market to optimize the supply and demand pattern and improve the utilization rate of production capacity.
Benefiting from the advantages of its own location layout and large-scale operation, Conch, China Resources, Tapai and other regional leading enterprises have been deeply engaged in the market of Western Guangdong and Dawan District for many years, with outstanding territorial service capabilities, and are more competitive in the bidding of engineering building materials.
