175 was from Jalan Ahmad Ibrahim to Prince Edward Road. Its
terminal was near the junction of Jalan Ahmad Ibrahim, Upper Jurong
Rd and Tuas Rd. Last time, there was also 175A. It started from
where 175 terminate and went to the end of Tuas Rd, where Tuas
Village was located.
Jurong Rd starts from Upp Bt Timah Rd, adjacent to the Bukit Timah
Fire Station, and stretched all the way to Jalan Bahar/Jalan Boon
Lay. After that junction, the road is called Upper Jurong Road
until the junction with Jalan Ahmad Ibrahim. After that, the road
is called Tuas Rd which led to Tuas Village near the sea.
The terminal at Jalan Ahmad Ibrahim was later relocated to Pioneer
Rd and therefore named Tuas Terminal. When Jurong Road was broken
up in the 1980s, 175 was amended to follow the current 174 route.
By 1989, it was amended to start from Bukit Batok Interchange and
loop at Pioneer Rd. A year later, it was shortened to loop at
Jurong West St 91 before finally being withdrawn in the 1990s.
