Across a lush valley near Shenzhen, the Gaofeng Stream Bridge cuts a striking figure. This isn’t just any bridge. It’s a testament to innovative engineering, the first of its kind in China. The Gaofeng Stream Bridge, part of the revitalized Guangming OCT Trail, is a stress-ribbon bridge. This means its deck is supported by two high-strength steel ribbons. These ribbons transfer the bridge’s weight directly to the strong abutments. They also form part of the walkway surface itself, along with precast concrete elements.
The Gaofeng Stream Bridge spans a 30-meter-deep valley, connecting two paths of the Guangming Trail. The architects cleverly designed a two-span system with one inclined column. This minimizes the bridge’s overall span and controls the slope of the deck. It also creates a high point on the bridge, offering stunning views of the surrounding valley. Imagine standing there, taking in the vista. The innovative design minimizes the bridge’s impact on the surrounding mountainous landscape. The sleek steel ribbons and concrete elements blend seamlessly with the natural beauty of the area.
The railing of the Gaofeng Stream Bridge is another example of its clever design. A stainless-steel cable net, connected to embedded steel elements in the precast concrete slabs, forms a secure yet visually light barrier. This allows for unobstructed views of the valley below. The entire structure appears to float effortlessly above the landscape, a ribbon of steel and concrete woven into the natural tapestry of the valley. The Gaofeng Stream Bridge is more than just a crossing. It’s a work of art, a symbol of human ingenuity and a harmonious blend of engineering and nature.
