Service 173 is a residential trunk route connecting the housing estates of Bukit Batok and Clementi, and the private estates of Hillview, Hume, Upper Bukit Timah, Toh Tuck and Lorong Kismis to Bukit Batok and Clementi Town Centres. Much of its route serves residents of private estates and condominiums along its route, and it is the only SMRT bus service at Clementi Bus Interchange.
As the route covers low-density estates, demand is relatively low during most parts of day, but particularly high during the peak hours. Between Bukit Batok and Clementi, Service 106 offers a faster journey as compared to this route.
Formerly a Singapore Bus Service (SBS) route since the 1970s, the route was transferred to Trans-Island Bus Service (TIBS) in 2000 and has been operated by SMRT ever since. High capacity articulated / double-deck buses are not deployed due to insufficient demand and the many narrow roads within private estates which the route serves.
A shortworking trip, Service 173A, will operate after the last bus has departed Bukit Batok Interchange to connect residents to the housing estates at late hours. During Eves of Public Holidays, last bus timings of Service 173A will be extended to complement the extension of train operating hours.
To increase connectivity to the Downtown Line Stage 2, from 27 December 2015, Service 173 towards Clementi will skip Jalan Anak Bukit via a new bus only right turn lane junction at Upp Bukit Timah Rd, to continue southbound on Upp Bukit Timah Rd before turning right to Jalan Jurong Kechil. It will call at a new bus stop, Upp Bukit Timah Rd (42099 Beauty World Stn) while skipping 3 bus stops along Jalan Anak Bukit and Upp Bukit Timah Rd (Northbound).
As such, Service 173 towards Clementi and also Bukit Batok will call at Beauty World MRT Station twice; once along Jalan Jurong Kechil and once along Upp Bukit Timah Rd. There are no route changes for Service 173 towards Bukit Batok.
