Beneath the heart of a Swiss city lies a 440-meter-long underground bike tunnel, originally designed for car traffic. Transformed into a sustainable cycling route costing over Rp700 billion, it now features LED lights, secure bike parking, and surveillance cameras—making it a fast, safe, and eco-friendly option for urban commuters.
