Central–Mid-Levels escalators Hong Kong 中環至半山自動扶梯

The Central-Mid-Levels escalator and walkway system in Hong Kong are the longest outdoor covered escalator system in the world. The entire system covers over 800 metres (2,600 ft) in distance and elevates over 135 metres (443 ft) from bottom to top. It was constructed in 1993 to provide a better commute by linking areas within the Central and Western District on Hong Kong Island.

Hong Kong Island is dominated by steep, hilly terrain, which makes it the home of some rather unusual methods of transport up and down the slopes.

Since it was officially opened to the public on 15 October 1993, the escalator system has played a very important role in pedestrianising the Western District. It links Queen's Road Central in Central with Conduit Road in the Mid-Levels, passing through narrow streets. The daily traffic exceeds 55,000 people, although originally forecast 27,000. At Queen's Road Central, the Central–Mid-Levels escalators system is connected through Central Market to the Central Elevated Walkway, an extensive footbridge network.

The escalator system is 800 metres (2,600 ft) long with a vertical climb of 135 metres (443 ft). The total travel time is twenty minutes, but most people walk while the escalator moves to shorten their trip. Due to the geographical situation, the same distance is equivalent to several miles of zigzagging roads if travelling by car. It consists of twenty escalators and three inclined moving walkways. According to Guinness World Records, these escalators together form the longest outdoor covered escalator system.

The escalators daily run downhill from 6:00 a.m. to 10:00 a.m. and uphill from 10:30am to midnight. Apart from serving as a method of transporting, the system is also a tourist attraction and has restaurants, bars, and shops lining its route. There is an entrance and exit on each road it passes, often on both sides of the road.
