The Dezhou-Shangrao National Expressway from Hefei to Zongyang section

The project prioritised technological innovation, making significant contributions to green environmental protection, energy efficiency, and carbon reduction in the highway industry.

The project introduced numerous groundbreaking technologies, with 18 new innovations proposed for the first time. These include pile-plate roadbeds, modular combined cable-stayed bridges, and segment-assembled light T-beams, driving forward the industrialisation of road construction and setting new benchmarks for the industry.

To address challenges such as land scarcity and environmental concerns, the project integrated advanced construction methods that significantly reduced wastewater, waste residue, and dust pollution. These solutions effectively mitigated the environmental impact of highway construction while optimising land use.

The project also delivered remarkable cost, energy, and carbon savings. Innovative technologies, such as steel plate combined beams and high-strength precast hollow piers, led to a 22% reduction in concrete consumption and a 25% decrease in carbon emissions, resulting in overall cost savings of $110 million.

Beyond its environmental and economic impact, the project has generated significant economic and social benefits. Many of its original technologies have already been implemented in 12 major infrastructure projects, collectively yielding $370 million in economic benefits. This achievement has positioned the project as China’s first industrialised intelligent manufacturing technology demonstration project under the Ministry of Transport. By integrating consultation, design, industrialised construction, aesthetics, and scientific research, the project stands as a model of excellence in modern highway development.
