Fuzhou Urban Forest Trail, also known as Fudao, is the first aerial forest trail in China and the longest aerial forest trail in Asia. Fudao adopts the hollow steel frame design pioneered in China, and the main body is composed of hollow steel tube truss, with the main shaft length of 8.2 km and the total length of the loop line of about 19 km. The contractor China Yeyi Company follows the concept of "maximizing social, economic and environmental benefits".

By using innovative technical measures such as mules and horses, artificial transportation materials, mountain elevated hoisting and assembling, and through the coordination and unity of minimally invasive ecology and humanized construction, the aerial forest trail will be built on the fragile ridge, and a landmark project integrating ecology, functionality and practicality will be created to provide citizens with a good place to exercise and enjoy the scenery.

Four difficulties in the construction of forest trails

1, using primitive mules to transport building materials. It is not easy to build a forest trail with a length of 19 km. In order to protect the original mountain and ecology as much as possible, the principle of "appropriate spending, less damage and original ecology" was adhered to in the construction process. The construction party only excavated a construction access road with a width of more than 1 m, and hauled construction materials such as sand and cement with original transportation tools such as donkeys and mules.

2. The plank road components are prefabricated in Hangzhou and then assembled on site. Because large machinery can't enter the mountain, the steel structure members of the plank road can only be prefabricated in the factory, then transported to the site for assembly and tightened with high-strength bolts. In order to protect the original ecological environment, the welding machine is not used for welding on site, so the construction accuracy is very high.

3. Construction is similar to laying a railway, which is assembled one by one. In addition to transporting building materials by donkeys and mules, due to the limitation of conditions, the plank road steel structure has to be constructed "skillfully", similar to laying railways and assembling them one by one.

4. It is not easy to coordinate land requisition and demolition. Because many of the mountains that have been "walked" by the plank road are in an undeveloped state and are currently used by many units, land use needs to be coordinated in many aspects.
