Route History

Service 171 is an inter-town route serving between the areas of Yishun, Bukit Panjang, Upper Bukit Timah, Bukit Timah, Newton, Orchard Road, Bras Basah and Marina Centre. It is a key inter-town connection between the towns of Yishun and Bukit Panjang, via BKE and Mandai Road, with no other public bus route offering a faster route. It was also well-patronized between the Orchard area and Bukit Timah with few duplicating routes before the Downtown Line Stage 2 opened.

In addition, the service provides bus connections to many institutions along the Dunearn Road / Bukit Timah Road academic belt. A large portion of its route runs parallel to Service 67 and 170 (between Newton and Bukit Panjang), as well as the Downtown Line Stage 2. Demand is moderate throughout the day but high during peak hours (especially between Bukit Timah and the City.) and during school dismissal hours. High capacity bendy buses are deployed occasionally, especially during special occasions such as route diversions and festive seasons.

This service plies a short express sector on the Bukit Timah Expressway (BKE), between Mandai Road and Bukit Panjang Road. Despite sharing the Yishun – Marina Centre connection with Service 857, it plies a much longer route, serving Bukit Panjang and (almost) the full stretch of Upper Bukit Timah & Bukit Timah Road.

No boarding and alighting is allowed at Marina Centre Terminal. The last stop for Marina Centre bound buses is at Raffles Boulevard (02089 Pan Pacific Hotel), and the first stop for Yishun bound buses is at Raffles Avenue (02101 Bef Temasek Ave).

Formerly a Singapore Bus Service (SBS) route since the 1970s, the route was transferred to Trans-Island Bus Service (TIBS) in 1995 and has been operated by SMRT ever since.

Double Decker Bus Deployments

On 24 August 2015, SMB5059J (Alexander Dennis Enviro500) performed Service 171 in the evening as part of a crossover slot (969S151). On its maiden trip from Yishun to Marina Centre, the bus was withdrawn from revenue service at Bukit Panjang by the Operations Control Centre (OCC), which was likely due to the route not being officially certified as ready for double-decker deployment.

Another incident happened on 08 December 2016, where a MAN A95 Bus (SG5744S) performed Service 171 for several trips before being pulled out of service.

From 12 August 2018, double-decker buses will be deployed on high-capacity bus slots on Service 171 on Sundays / Public Holidays instead of articulated buses.

DTL2 Bukit Panjang Bus Service Enhancements

As part of DTL2 Bukit Panjang Bus Service Enhancements, Service 171 towards Marina Centre will call at a new bus stop, Bt Panjang Rd – Blk 184 instead of Bukit Panjang Rd – Blk 183 from 27 December 2015. Yishun bound Service 171 will still call at Bt Panjang Rd – Blk 604.

Opening of Bukit Panjang ITH Bus Service Amendments

As part of the Bus Service Amendments for Bukit Panjang ITH Opening, Bus Service 171 will skip the pair of bus stops along Jelebu Rd, serving Opp and Outside Bukit Panjang Plaza to “better manage traffic flow” outside Bukit Panjang Integrated Transport Hub from 04 Sep 2017.

The morning special departures from Jelebu Rd both towards Yishun and Marina Centre will also be adjusted to start from the next stop.

This amendment was reverted effective 25 Feb 2018 with Service 171 calling at a pair of bus stops (Blk 180 / Opp Blk 180) along Jelebu Road.

Special Departures:

  • Bt Panjang Rd (Blk 604)  Yishun Int
    Weekdays: 0540hrs & other trips before 0640hrs
    Saturdays: 0615hrs & other trips before 0640hrs

    Please be considerate for 171 commuters & not easing traffic flow along Jelebu Rd, especially during rainy days. We have to walk a long way back to Bukit Panjang Plaza!
