Route History

Service 859 is a residential trunk route linking many parts of Sembawang Estate with Yishun and Sembawang MRT stations, as well as various neighbourhood amenities. It is one of few bus routes to serve residents within the small Sembawang estate. By making one round around the Sembawang estate before terminating at Sembawang Int, passengers can board the bus at to appropriate bus stops along Sembawang Drive or Sembawang Vista if they intend to head towards Yishun directly.

As a residential route, demand is moderate to high throughout the day, but high capacity double-deck / articulated buses are not deployed as rigid buses cope well with loading levels. From 17 Aug 2014, two new supplementary route variants, Services 859A and 859B, were introduced under the Bus Service Enhancement Programme (BSEP). As a result, early morning downroutes from Sembawang Vista (Blk 309) and Shortworking Trip 859A will cease to operate.

Route Variants: 

  • Service 859A: Sembawang Bus Interchange ↺ Admiralty Link (Loop)
    Counter-clockwise loop
  • Service 859B: Sembawang Bus Interchange ↺ Admiralty Link (Loop)
    Clockwise loop

Fare: Charges normal trunk fares. See Fare Table.

Fleet: Service 859′s fleet comprises of a majority of MAN A22s, with some Mercedes-Benz O405s.

  1. hi, please let me know the earliest timing smrt bus 858 will reach / depart from opp blk701a yishun avenue 5 on 01 january 2015. thanks.

    • Dear Merlyn,

      SMRT does not publish their bus timetable for their bus services online. Do check the bus information panel at the bus stop for the first bus timing under “Sundays / Public Holidays”.

  2. Understand that Yishun Interchange have installed Tv screens in various berth, so that passengers can check the timing for the next bus arrival. However, and sadly, waited for so long, they still failed to reflect the timing for bus 859.
    And I am not sure what is the reason, that only 859 is not reflected.
