The roots of the city come from nature, and while mankind continues to destroy the environment in order to develop, it is also depleting and damaging our ecosystem. 

 The concept of Roots of the Earth, based on the original soil of the site, grows a new type of urban ecological and structural space that grips the two mountains and naturally integrates with their ecosystems, which symbolizes and foreshadows a new ecosystem of fusion and diversification, a multi-layered tandem. The design re-stitches the Merrill Hill and Silver Lake Hill, which were originally separated by the city roads. A three-tiered eco-rest bridge meanders through the air between the two mountains, providing a continuous and safe passage for wildlife and a unique experience for visitors. During the design process, different sizes and habits of wildlife were taken into account to minimize and avoid conflicts between visitors and animals, as well as with urban construction and highways. The eco-bridge on the bottom level increases the width to 45 meters, 1.5 times the width of Meiguan Road, which can provide a wider and safer ideal habitat and migration environment for wildlife. The middle level is constructed with lightweight structures to create a fabric pathway for visitors to walk through the canopy layer, which allows them to watch the wildlife passing through the corridor below from the bridge.

The pedestrian steel bridge is tensioned with a suspended structure as well as a support structure to the upper thin concrete shell, and the lower thin concrete shell.
