Green Bus served Bt Timah areas or more commonly today's 17X
series svs.
To take note was this was the original 1970s bus routes when SBS
was formed
170: Queen St - JB
Route remained unchanged over the years on Singapore roads.
171: Queen St - Mandai Rd/ Sembawang Rd (Somewhere near Nee Soon
Camp, dun forget back then there wasn't Mandai Ave constructed
yet)
Route was later extended to Yishun New Town by SBS. Later on in
early 1990s, the service was amended to serve Orchard & Marina
Centre. Handed to Tibs in 1995.
Under Tibs, route was amended to use BKE & Bt Panjang Rd
instead of Mandai Rd, Woodlands Rd, Cashew Rd in 1999.
172: Lim Chu Kang - Shenton Way
Route was later shortened to Jln Anak Bt/ Upp Bt Timah due to
MRT (Not too sure what exactly happened). Later with MRT
1992/ 1993 rationalisation, with the withdrawn of Sv 206 (Lim
Chu Kang - Boon Lay), route was amended to Boon Lay instead of Lim
Chu Kang. Handed to Tibs in 1999.
173: Princess Elizabeth Estate - New Bridge Road
Route was later amended into Bt Batok New Town as well as merger
with Sv 205 (Clementi - Toh Tuck Rd) to form today's 173 (Bt Batok
- Clementi) skipping CBD. Handed to Tibs in 2000.
174: Nanyang University - New Bridge Rd
Route was later amended to Boon Lay Int in 1990 due to Jurong
Bus & MRT rationalisation.
175: Tuas/ SAFTI - Shenton Way
Route was apparently shortened to become Bt Batok - Jurong West
St 92 (Loop). Withdrawn. Later on in 1993 reintroduced as Lim Chu
Kang - Upp Bt Timah (MINDEF). Handed to Tibs in 1999.
As for Svs like 176, 177, 178, 179 they were added when SBS came
into the picture
