Bus Service 181 is a trunk service that connects residents of Jurong West Neighbourhoods 7, 8, and Wenya Estate (Neighbourhood 2) to Boon Lay MRT/Bus Interchange. The route travels along Jurong West Street 64 and 75, then Jurong West Avenue 5 and 3, where it makes a U-turn at the end before returning to Boon Lay.
Although it operates entirely within the Jurong West area, Service 181 is classified as a trunk service rather than a feeder service, for reasons that remain unclear. Since its introduction in 2005, no route extensions beyond Jurong West Avenue 3 have been made.
On school term weekday mornings, from 6:30 am to 7:45 am, Service 181 is replaced by its route variant, Service 181M, which loops at Jurong West Street 23. This variant provides access to Corporation Primary School, which is otherwise only served by Bus Service 185. During this time, Service 181 does not operate while Service 181M is in service.
On the eve of public holidays, operating hours will be extended to align with the extended train service hours. Extended last bus timings will be provided by the operator closer to the affected day.
Future Plans:
Service 181 is planned to be extended to Tengah Bus Interchange as part of the Land Transport Authority’s Bus Connectivity Enhancement Programme (BCEP).

As a Tengah resident, and seeing the concerns in our community groups – Tengah being a car-lite town, or at least being envisioned as one, requires probably a different set of lens to plan. Infrastructural completion takes (a long) time, and while waiting for JRL, and the PIE / KJE interchanges at Jurong / CCK, we genuinely hope for more route enhanced buses. And it’s not just about one bus route seeming convenient to pass through Tengah and therefore it should – From bus 97 example I’m very hopeful that authorities know what they are doing, because many online comments before the announcement guessed or suggested 174, 171, etc (can’t recall all), and 97/97e was such a pleasant surprise (few if any, guessed it). We have residents hoping for more direct routes to other areas (we do our part collectively to voice out to authorities), and hopefully before JRL completes, given the extended delay, we could see light in the tunnel for more fantastic route improvements.
I have just walked the ground, at Bulim.
3 pairs of bus stops confirmed:
– at Bulim Walk, immediately next to Jurong West Avenue 3.
– at Bulim Drive, next to Bulim Square Tower 1.
– at Bulim Drive, next to the edge of Bulim bus depot.
Bulim Drive next to Bulim bus depot is still under construction (no road constructed yet).
Anyway, with this, it is clear that the routing in Bulim will be: Jurong West Avenue 3, Bulim Walk, Bulim Drive, Bulim Avenue.
The section of Bulim Drive, earliest also need about six months to build, because other than road, also got the skywalk above it.
Nonetheless, Bulim Square Towers, already completed, but relatively empty, already got two food establishments going to open (marry brown and luckin coffee).
They may still let 181 go into Bulim industrial area now, since it is 90% completed, and they really need people to go to Bulim Square Towers, but definitely will go a temporary route (Bulim Green and Bulim Street), since got one section of Bulim Drive still not ready.
Whereas at Tengah, the alignment should be what is stated at the HDB material.
Actually, if they are waiting for that section of Bulim Drive, which is still under construction (still digging the ground at the moment), 181 extension is unlikely going to happen in 2026. Probably in 2027.
Perhaps, we should temporarily not think about 181 extension into Tengah for now. It will probably extend into Bulim industrial area first, and loop via Bulim Green and Bulim Lane 2 – just to connect to Bulim Square. With no bus stop at Bulim Green and Bulim Lane 2 since it is just temporary. Then, some time in 2027, or later (when Tengah Way is connected to Jurong West Avenue 2), then 181 extend again to Tengah.
In other words, 181 extension into Tengah may be announced too early. The eventual route extension will probably be Bulim Walk, Bulim Drive, Bulim Avenue and Jurong West Avenue 2 in Bulim industrial area, and Tengah Way, Tengah Garden Avenue and Tengah Garden Boulevard in Tengah industrial area. Approximately 5.6km route extension eventually, extending 181 length in one direction from 3.3km currently to 8.9km eventually – which is still short, and definitely still can extend somemore towards Choa Chu Kang or Bukit Panjang next time.
