This bridge’s key differentiator is its eco-friendly design and inclusive sightseeing experience. The bamboo-steel composite decking is made from fast-growing moso bamboo, which is 100% renewable and has a carbon footprint 60% lower than traditional wood decking. It offers wear resistance and slip resistance, with a surface treated to resist mold and insect damage in humid forest environments. The main cables are coated with eco-friendly powder coating, containing no volatile organic compounds (VOCs), reducing air pollution during construction. The curved deck design provides unobstructed panoramic views, while transparent polycarbonate guardrails ensure safety without blocking the natural scenery. Barrier-free ramps with a 1:12 slope and tactile paving enable easy access for wheelchair users and elderly visitors. A solar-powered lighting system is installed along the sidewalks, providing energy-efficient illumination at night while reducing reliance on grid power. The bridge’s structural health monitoring system uses low-power sensors to minimize energy consumption, aligning with eco-friendly infrastructure standards.
The total bridge length is 380 meters, with a 180-meter main span and two 100-meter side spans. The deck width is 4.5 meters, including a 3-meter pedestrian zone and 0.75-meter barrier-free ramps on both sides. The single tower is 45 meters tall, with a curved steel structure coated in a matte green finish to blend with surrounding forest vegetation. The main cables have a diameter of 55mm, composed of 25 strands of 127×0.6mm galvanized steel wires with eco-friendly powder coating. The bamboo-steel composite decking is 60mm thick, with a friction coefficient ≥0.85 in dry conditions and ≥0.7 in wet conditions. It meets Grade 12 wind resistance standards, capable of withstanding 32.7 m/s wind speeds. The design service life is 50 years, with annual corrosion rate ≤0.01mm under C4 environmental conditions. Solar-powered LED lights are installed every 10 meters along the deck, with a battery life of 72 hours for continuous operation during power outages. Barrier-free rest areas with benches are placed every 50 meters to accommodate tired visitors.
