Service 858 is a residential and inter-town route plying between the housing estates of Woodlands, Sembawang, Yishun, and stretching far east to Changi Airport. Much of its route plies express sectors along the Seletar Expressway (SLE), Tampines Expressway (TPE) and Pan-Island Expressway (PIE). At 73.4km long, it is the longest bus route in Singapore (after the shortening of NightRider NR7 in 2014). The ride from Yishun to Changi Airport takes about 38 minutes in smooth traffic.

At 2314hrs daily, the bus leaving Woodlands Bus Interchange will terminate at Changi Airport PTB2 Basement. From 2330hrs to 0030hrs daily, buses leaving Woodlands Regional Int will be renumbered as 858A, and terminate at Yishun Ave 2 (Blk 923). From Changi Airport PTB2, the last bus returning to Woodlands departs at 0023hrs daily.

As the quickest transport link from housing estates of the North to Changi Airport, as well as providing valuable inter-town connections in the North, this service encounters moderate to high demand throughout the day. Due to its extended length, bus bunching is relatively common, which BSRF is attempting to minimize.

Changi Airport:

Changi Airport Passenger Terminal Buildings (PTBs) 1, 2 and 3 have their bus stops integrated into their basement levels, which also serves as a cargo loading and unloading bay. Security checks for any unattended or suspicious articles are carried out before a bus enters each Airport PTB.

On occasions when Changi Airport basement is closed, buses will be diverted to T1/T2/T3 Departure Drive.

Special Departures:

  • Yishun Avenue 2 (Opp Yishun Sports Hall)  Woodlands Temp Int
    Daily: 0530hrs – 0700hrs
    Caters to inter-town commuters before the first bus arrives from Changi Airport.

Shortworking Trips:

  • Service 858A: Woodlands Temp Int → Yishun Ave 2 (Aft NorthPoint Shop Ctr)
    Daily: 2330hrs – 0030hrs
  • Service 858B: Jalan Kayu (Bef Seletar Camp G) → Jalan Kayu (Aft Seletar Camp G), via Changi Airport
    Weekdays AM Peak Hours

    Could I suggest that 858 be amended to include a deviation from TPE between Loyang Ave & PIE via Loyang Ave – Old Tampines Rd – Flora Rd – Upper Changi Rd North – PIE.

    This would provide Changi residents direct access to Changi Airport/ Jln Kayu/ Yishun/ Sembawang & Woodlands.

    This would also provide the North/ North-East a one stop transfer at Upp Changi Rd North to the following destinations:
    – Simei
    – SUTD
    – Changi Prison
    – Expo
    – Changi Village

      They can consider what’s mentioned above. Bedok will also be good despite having svc. 24 and the changi airport line. I hope 24 would also have bendies depending on the new seletar pckg. operator and LTA.
