Station expansion and new lines Admiralty station was expanded to serve two additional lines - the on level L6 and the on level L5. The South Island line platforms opened on 28 December 2016, after a public open day on 24th of that month, giving residents in the Southern District quicker access to Hong Kong Island's central business district.
