Southern Network News (reporter Zheng Xuyan correspondent Guangdong Jiaotong Zong) on December 9,The second phase of the Hezhou-Gaolan Port Expressway was officially completed and put into trial operation, with a mileage of about 165 km, marking the completion of the last piece of the "puzzle" of the Hegang Expressway and the realization of the whole line.
Zhuhai Hezhou to Gaolan Port Expressway Project connects Hong Kong and Macao in the east and reaches the west of GuangdongFull length approx34.5 km, to be built in two phases. The starting point is connected to the Jiangzhu Expressway, and the end point is located at the Gaolan Port Expressway. The ratio of bridges and tunnels to the whole line is 8478%, with 18 extra-large bridges and 26,381 meters of bridges and 2,437 tunnels5 meters 2 blocks, 7 interchanges, 1 service area.
As a key project to improve the national highway network "Pearl River Delta Regional Ring Road", in 2011, Hegang Expressway started the pre-feasibility study with the "Hong Kong-Zhuhai-Macao Bridge West Extension Project", and the project was approved by the province in 2016, and the first phase of the Hegang Expressway project officially started in November 2017, and the project Jiangzhu Expressway to the airport high-speed section was opened to traffic simultaneously with the Honghe Bridge in December 2020On September 28, 2021, the first phase of the project was opened to trafficOn July 9, 2022, the vehicle toll was officially collected, and the task of "fast track" of the air show was successfully completed twice. In July 2019, the second phase of the Hegang Expressway project officially started, and in October 2023, the civil engineering, road surface, traffic safety, mechanical and electrical and ancillary works will be completed, and the conditions for opening to traffic will be metIt will be put into trial operation on December 9, 2023
During the construction of the project, the project team actively carried out technological innovation and scientific research, and vigorously promoted it in roadbed, pavement, bridges and tunnels, housing construction, greening, mechanical and electrical, and traffic safety projects"Four new technologies" and "micro-innovation".Technology application, with technological innovation and management innovation to continuously improve the quality of engineering entities, to achieve excellence and efficiency, to create high-quality projects, model projects, safe projects, clean projects, and strive for the "National Quality Engineering Award".
As of now,The second phase of the project has won 7 enterprise and provincial and ministerial QC achievement awards, 6 provincial and ministerial micro innovation achievements, 19 authorized patents (18 utility models, 1 invention), and 4 science and technology awards。The project has successively won the honorary title of "Safe Construction Site" Typical Demonstration Project of Guangdong Province's Annual Highway and Water Transportation Project, and was selected as the first batch of "Green Highway" Construction Typical Demonstration Project in Guangdong Province and the pilot project of "Transportation Power" construction in Guangdong Province, and its quality and safety management work has been widely praised.
Zhuhai leaps east and west and then speeds up
As the second east-west traffic artery in Zhuhai, the Hegang Expressway crosses Jinwan, and Zhuhai's east-west crossing is speeding up againGongbei to Gaolan Port can be reached in 40 minutes。After the project is completed and opened to traffic, it will be interconnected with a number of expressways and municipal roads, connecting the main urban area of Zhuhai, the central urban area of the western part of Zhuhai and the Gaolan Port Economic ZoneIt has an important function of cross-border river crossingIt is an important collection and distribution channel for the two ports of Zhuhai and the planned Hezhou North Railway Hub Center, laying a solid foundation for Zhuhai's westward expansion, urban expansion and quality improvement, and promotion of regional industrial transformation and upgrading.
