The Central–Mid-Levels escalator and walkway system in Hong Kong is the longest outdoor covered escalator system in the world. The system covers over 800 m in distance and traverses an elevation of over 135 m from bottom to top. It opened in 1993 to provide an improved link between Central and the Mid-Levels on Hong Kong Island.
The escalators at top stage of the escalator system between Robinson Road and Conduit Road have been replaced, and went operational on 11 July 2018. In early 2019, three refurbished escalators between Mosque Street and Robinson Road went operational. In June 2019, two replaced escalators between Caine Road and Elgin Street opened to the public. The escalator between Gage Street and Wellington Street is currently under refurbishment.
