Route History

Service 177 is a peak-hour inter-town route connecting Bukit Batok, Hillview and Bukit Panjang, as well as providing bus connections to Ministry of Defence Headquarters (MINDEF HQ @ Gombak Drive) and its surrounding army camps. Formerly a full-day service, it now only operates during weekday peak hours with moderate demand.

In 2012, this route was converted from bidirectional operation to unidirectional operation, looping at Jelebu Road when the former Bukit Panjang Interchange was demolished to make way for the new Bukit Panjang Integrated Transport Hub.

Formerly a Singapore Bus Service (SBS) route since 1989, the route was transferred to Trans-Island Bus Service (TIBS) in 1995 and has been operated by SMRT ever since. High capacity articulated / double-deck buses are not deployed due to insufficient demand.


Special Departures:

  • Bukit Panjang Road (Blk 604) → Bukit Batok Int
    Weekdays: 0613hrs – 0636hrs

Shortworking Trips:

  • Service 177A: Bukit Batok Interchange → Jelebu Road (Bt Panjang Plaza)
    0828 – 0840, 1806 (Weekdays)

Service 177A operates as a half trip of Service 177, ending at Bukit Panjang. Buses that operate on 177A are usually taken out of service after finishing their runs.

Fare: Charges fares for regular trunk services. See Bus Fares for exact fares.

Fleet: Service 177′s fleet fully comprises of MAN NL323F buses operating on split-shift. They will perform crossover trips on Service 925 after Service 177’s operating hours.

  1. Anyone knows if public can take 177 can travel into Mindef premises? Or got to alight like those buses going to Changi Airport Cargo Complex?
