Service 177 is a weekday 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 was operated by SMRT Buses until its it was re-allocated to the Bus Contracting Model (Bulim Bus Package) in May 2016 and operated by Tower Transit since then. At the same time in May 2016, Shortworking trip 177A was withdrawn.
Service 177 calls at MINDEF CP, Gombak Dr both towards Jelebu Rd (Bukit Panjang) and Bukit Batok.
Temporary Amendment to skip Hillview Link
To facilitate the construction of NS Hub, Hillview Link would be temporarily closed from 23 November 2020. As a result, Service 177 would be temporarily amended to ply an express sector along Hillview Rd and Upper Bukit Timah Rd (between Hillview Rd & Gombak Dr).
There would be no change in bus stops served for Service 177.
At Hillview Ave, buses towards Bukit Panjang will call at Bus Stop 43151 – Opp Glendale Pk Condo, while buses towards Bukit Batok will call at Bus Stop 43159 – Bef Glendale Pk Condo. In addition, only buses towards Bukit Batok will call at Bus Stop 43721 – Blk 319 along Gombak Dr.
