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 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 At the same time, Shortworking trip 177A was withdrawn.

    I currently use bus 176 from Bulit Batok to Hillview and at 1830 to 1900 it is always over-full. I really would like to use service 177, but the last bus at 1820 prevents me from doing so. I finish work in Tuas at 1800, take the company bus to Jurong East, MRT to Bukit Batok; it means I arrive 1835-1840 at BB interchange, too late to get the last bus. I often see people waiting at the stop after the service has finished. Might it be possible to extend the service?
