In the early morning of June 7, 2022, the main span of the Jingning Viaduct of Zhejiang Jingwen Expressway closed smoothly, and the Jingning section of Jingwen Expressway was fully connected. The Jingning Viaduct has a total length of 715 meters and is a two-way four-lane expressway with a design speed of 80km/h.

Combined with the positioning and design of the landscape bridge, Jingning Viaduct adopts the asymmetric single-box five-chamber main beam structure of a rare single-pylon cable-stayed bridge in Zhejiang. Due to the complex process and difficult construction technology, the project department carried out technical research and process innovation. "In terms of construction engineering technology, we adopt new technology and new technology. For example, we use the slag in the tunnel to process it into machine-made sand, and turn waste into treasure and use it in high-grade concrete." Bao Bao, deputy chief engineer of Jingwen Expressway No. 1 project Chun Qian said.

The Jingwen Expressway has a total length of about 68 kilometers and traverses the mountainous areas of southern Zhejiang. It is one of the most difficult expressways in Zhejiang Province. As the last section of the national expressway network Liyang-Ningde Expressway in Zhejiang, after completion, the journey time from Jingning to Wencheng will be shortened from 2 hours and 30 minutes to 40 minutes.Editor/Ma Xue
