Service 857 connects the residential estates of Yishun, Khatib, and private estates around Yio Chu Kang Road, with a fast connection to the City areas of Little India, Bras Basah, Suntec City and Marina Centre. The route incorporates an express sector on the Central Expressway (CTE) between Yio Chu Kang Road and Jalan Toa Payoh in both directions, making it a popular connection between the North and the City.

Demand for the route is moderate during off-peak hours but very high during peak hours, as residents commute to and from the City and various industries along Yio Chu Kang Road. High capacity double-deck buses were deployed from 26 April 2015.

Introduced in 2001 by Trans-Island, the route has not undergone any amendments since, except for a diversion to Prinsep Street when a portion of Bencoolen Street was closed for Downtown Line construction between 2011 – 2016.

Between 2241hrs and 2330hrs daily, buses leaving Yishun Temp Int will terminate at 02151 Temasek Boulevard (Suntec Convention Ctr). The last bus returning to Yishun leaves Suntec City at 2328hrs.

Fare: Charges basic distance fares. See Bus Fares. Calculate your bus fare using LTA’s fare calculator on here.

One thought on “SMRT Bus Service 857

  • 2 January 2018 at 11:14 AM

    boarded 857 at Bras Basah to look home to Upper Serangoon/St. George’s Road last night after 7pm (probably 7:15pm).

    why was 857 instructed to be driven at such a slow pace when the bus is filled with commuters from Little India? when bus is filled up, why is bus told “to be at crawling speed” (sorry, i have no other expression however it is ludicrous decision).

    and this was a single-deck … i can understand if 857 happened to be double-deck, in fact for weekends and public holidays, double-deck buses seem to be needed especially when foreign workers are returning home (single-decks simply is insufficient for the mass numbers at Little India).
