Hong Kong’s tall buildings are linked through a system of escalators and moving sidewalks, including the Central Mid-Levels Escalator, the longest outdoor, covered escalator system in the world. The 2,600-foot (800-meter) structure, consisting of 20 escalators and 3 moving sidewalks, allows commuters and tourists to high-rise-hop without ever descending to the ground.
