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 Int will terminate at 02161 Temasek Ave (Promenade Stn). The last bus returning to Yishun leaves Promenade Stn at 2331hrs on Weekdays, 2324hrs on Saturdays and 2330hrs on Sundays / Public Holidays.
