On January 25th, a critical milestone was achieved in the expansion project of the Yongjin Expressway's Shaoxing section managed by Zhejiang Transportation Group. The project's first traffic diversion was successfully completed as vehicles began to flow orderly onto the newly constructed Nianzhai temporary passageway. This provisional route, stretching approximately 1.4 kilometers in length, will shoulder the crucial responsibility of maintaining the smooth flow of the major east-west freight artery, while also laying a solid foundation for the main construction work on the Nianzhai Bridge.
The Yongjin Expressway serves as a vital "Golden Logistics Corridor," seamlessly connecting the Ningbo-Zhoushan Port with the Yiwu International Port. With the sustained growth of the regional economy, the average daily traffic volume on this route has surged to 40,000 vehicles, of which trucks account for more than 55%. To alleviate congestion and enhance service quality, the comprehensive expansion project is being vigorously advanced. A primary challenge throughout this endeavor has been ensuring traffic remains largely uninterrupted and minimally impacted during the construction phase.
Adhering to the principle of "minimal or no lane closures," the project command headquarters broke away from traditional full-closure construction methods. After numerous on-site surveys and meticulous plan optimizations, a strategy was finalized to implement the traffic conversion in four distinct phases. This initial diversion was deliberately scheduled for the period of lowest traffic flow, proactively avoiding the peak hours of 6:00 AM to 11:00 AM towards Jinhua and 4:00 PM to 6:00 PM towards Ningbo, thereby minimizing the construction's impact on road users.
The Shaoxing section of the Yongjin Expressway expansion spans over 73 kilometers and is being upgraded to an eight-lane, dual-carriageway standard with a design speed of 100 kilometers per hour. Upon completion, the project is set to significantly boost the road's capacity and service levels, thereby strengthening the transportation backbone that supports regional economic and social development.
The successful execution of this traffic diversion not only provides valuable experience for the planned removal and widening of the mainline guardrails in 2026 and subsequent traffic management plans, but also signifies that the project's phased construction model—"advancing section by section, opening each completed segment for use"—is now firmly on track. Furthermore, this operation served as a practical test of the "Multi-party, Five-guarantee" collaborative工作机制. The project command headquarters, in close coordination with highway police, traffic law enforcement, operations management, and all participating construction units, worked in concert to conduct traffic guidance, diversion, and on-site control, achieving an effective balance between construction progress and road accessibility.
By implementing short-term, meticulously planned traffic management, the project aims to secure a long-term, overall enhancement in travel quality. This approach facilitates crucial infrastructure upgrades while tangibly safeguarding public mobility, exploring a practical pathway where major engineering projects and public welfare can advance in harmony.
