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

Service 859B was introduced as a full-day supplementary bus service as part of the Bus Service Enhancement Programme (BSEP) service improvements. Service 859A plies the same route as Service 859B 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.
