The Mid-Levels Escalator is a series of escalators and moving walkways located in the central district of Hong Kong. It connects the central business district to the residential area of Mid-Levels, making it easier for residents to commute uphill. The escalator system spans over 800 meters and is the longest outdoor covered escalator in the world. Opened in 1993, the escalator operates in a downhill direction during the morning rush hours and reverses in the evening. It serves as a vital transportation link, reducing the need for cars and helping to alleviate traffic congestion in the area.
