The Meilin Mountain - Yinhu Mountain Corridor Bridge will become an important part of the Shenzhen Mountain-Sea Connecting City Plan, integrating ecological connectivity and recreational experiences. During urban development, the originally connected mountain ridges were fragmented by an expressway and high-voltage corridors. Scientifically effective design interventions will innovatively balance biological migration corridors, hiking pathways, and city gateway experiences.
Firstly, the design starts from an ecosystem planning perspective, rebuilding the habitat foundation on both sides of the road. Using food chain mechanisms, it attracts animals to approach the bridge by maintaining shallow water puddles, offering rich vegetation layers, isolating disturbances like noise and light pollution along the path.
Secondly, the design forms a dual-layer, three-dimensional corridor for wildlife. A green-arched bridge is constructed above the expressway, with a well-planned layout of microhabitats suitable for various small mammals. Beneath the expressway, the existing culvert’s surrounding height difference is reduced, creating spaces conducive to the movement of reptiles and amphibians.
Thirdly, a lightweight pedestrian bridge is added above the ecological corridor bridge, enhancing the enclosure of the arch bridge and strengthening the experience of wildlife traversing through the forest. The existing mountain hiking trail system is connected with low-intervention methods, while the path leading to the culvert is concealed to avoid disturbing the wildlife corridor. Small service nodes and educational facilities are set at the bridgehead and along the bridge.
In terms of design approach, a light, thin facade language is used alongside a solid, thick plan language. The image of the suspension bridge echoes the form of high-voltage lines. In the details of the bridge deck, the design reflects the modern cityscape while maintaining a simple, low-intervention character.
