Bus Service 859A is a route variant of Bus Service 859. It duplicates Service 859 within the Sembawang residential estate, departing Sembawang Interchange and making a counter-clockwise loop via Canberra Rd, Admiralty Link, Sembawang Dr, Admiralty Dr and Sembawang Cres before terminating at Sembawang Interchange.

Service 859A was previously a short-trip service terminating at Opp Blk 315, Sembawang Vista (outside Sembawang Interchange), operating from 12:00am to 12:50am after the last bus of Service 859 towards Yishun has departed. Service enhancements as part of the Bus Service Enhancement Programme (BSEP) upgraded it to a full-day supplementary bus service. In addition, Service 859B was introduced, plying the same route as Service 859A in the opposite direction.

The A and B suffixes used do not represent these routes as Short-Trip Services, but as route variants of Service 859. Such route numbering is similar to the Green and White plates (G/W suffix) used on SBS Transit feeder routes to indicate different directions of travel.

Both routes were launched on Sunday, 17 August 2014, to improve bus connectivity within the Sembawang estate and aid with high passenger loading on Service 859. The routes connect to public amenities such as Canberra Community Club, Sembawang Library, Sembawang Mart, Sembawang MRT Station, Sembawang Secondary School and Sun Plaza.

During Eves of Public Holidays, as well as MRT Early Closure affecting Sembawang MRT Station, operating hours will be extended. Exact last bus hours are announced by Tower Transit closer to these dates.
