On August 31, 2022, in the Maweiting River Interchange Area, with the colorful smoke rising into the sky, the construction of the second expressway project of Fuzhou Airport officially started.

The project is built by the Communications Construction Group of Fuzhou Zuohai Group. It starts from the Maweiting River hub, passes through Changle Houyu, Tantou, Wenling, Hunan, and ends at Fugang Road, connecting with the airport North Jinchang Road. 24.3 km. After the project is completed, it will strengthen the traffic connection between the northern part of the urban area and Binhai New City, forming a south and a north double artery. By then, it will take only 45 minutes to go directly to Fuzhou Airport from the third ring park, via the Jinan to Mawei section of the G104 national highway, and the second airport expressway.

Two-way six-lane expressway standard

According to reports, the total investment of the project is about 9.763 billion yuan, and the planned total construction period is 42 months. Its main line adopts the standard construction of two-way six-lane expressway, with a design speed of 100km/h and a roadbed width of 33.5m. Among them, auxiliary roads are set up from Tantou Town to the end of the route, which adopts two-way four-lane secondary road and municipal function standard, with a total length of 11.9 kilometers and a design speed of 40km/h. The whole line has Tingjiang hub and 2 interchanges in Houyu and 4 entrances and exits in Jinfu, Houfu, Wenling and Hunan.

The bridge-to-tunnel ratio of the entire project line is as high as 91.4%. As the control project of the project, Min'an Bridge adds a beautiful scenery along the way. It adopts 3×60+716+3×60=1076m single-column double-tower double-cable plane mixed beam cable-stayed bridge, more than 200 meters high. The two main towers are supported on both sides of the Minjiang River (the Fuzhou side tower is 215m high and the Changle side tower is 226m high). After completion, the overall shape is vivid, like two large harps.

The Min'an Bridge with a main span of 716 meters and a side span of 180 meters is not only beautiful in appearance, but also ranks second in the world among long-span bridges of the same type after the bridge is completed. The smallest and the most difficult to construct. In addition, the standard width of the main beam of the bridge is 54.25m, the maximum bridge width is 59.25m, and the super-wide main beam section ranks the highest in China.

Tingjiang Tunnel is also an important part of the project. It adopts a large-span asymmetric small clear distance structure with 4 lanes on the left line and 3 lanes on the right line. The excavation width of the left line is 21.5m, the excavation width of the right line is 17.5m, and the , The clear distance between the right lines is about 8.5m, which is only 0.4 times the excavation width of a single hole. The person in charge of the on-site construction introduced: "Tunnels with large spans and small clear distances are rare at home and abroad. They have the characteristics of difficult construction, long periods and high risks, and put forward high requirements for tunnel excavation methods."

In order to facilitate the travel of the surrounding people, the Tantou Super Bridge, Wenling Super Bridge and Hunan Super Bridge pass through the town, and auxiliary roads are set up on both sides under the bridges. In order to improve the overall landscape effect of the bridge and integrate it with the surrounding urban landscape, the person in charge of on-site construction introduced that the lower structure of the bridge adopts large cantilever prestressed cover beams, "the large cantilever cover beam structure can make full use of the space under the bridge and set up auxiliary roads, Save project construction land."

Only 45 minutes from the park to the airport

According to the relevant person in charge of the municipal traffic construction, the second expressway of the airport will be connected to the Tingjiang section of the G104 national highway. After the project is completed, it will only take 45 minutes for citizens to travel from the park to the airport via the G104 national highway and the second expressway of the airport. The traffic connection between Binhai New City forms a "double artery" of one south and one north.

The relevant person in charge of Zuohai Group pointed out that the project passes through Mawei and Changle, and belongs to the "Central City-Eastern New City-Binhai New City" motor vehicle expressway, and is an important part of Fuzhou's "four horizontal and three vertical" express backbone network system. After the completion of the project, it will improve the collection and distribution system of Fuzhou Changle International Airport, optimize the grid layout of express roads inside and outside Binhai New City, promote Fuzhou to accelerate the construction of a modern international city, enhance the influence of the provincial capital city, drive development and regional competitiveness, and promote the urbanization of Fuzhou. The high-quality development of the circle is of great significance.

"In the next step, we will continue to improve the layout of expressways and promote Fuzhou to form a three-axis and three-corridor comprehensive transportation channel with the goal of enhancing the status of Fuzhou's national comprehensive transportation hub and striving to become an international transportation hub."
