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 was operated by SMRT until its it was re-allocated to the Government Contracting Model (Bulim Bus Package) in May 2016. At the same time, Shortworking trip 177A was withdrawn.
As part of the Bukit Panjang ITH Opening Bus Amendments, Service 177 was amended to call at Blk 180, Jelebu Rd instead of Bt Panjang Plaza, Jelebu Rd from 04 Sep 2017.
Service 177 calls at MINDEF CP, Gombak Dr both towards Jelebu Rd and Bukit Batok.
