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 since its launch in 2005 rather than a feeder service, possibly catering for a potential extension beyond Jurong West estate. Such an extension would only arrive in 2026, when it was extended to Tengah.
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.
Extension to Tengah:
On 9 February 2026, the Land Transport Authority announced plans to extend Service 181 to Tengah Bus Interchange under the Bus Connectivity Enhancement Programme (BCEP). The route amendment was eventually announced for 14 June 2026.
The route amendment will enhance connectivity to Bulim Industrial Estate and inter-town connectivity between Jurong West and Tengah. In addition, Service 181M will operate concurrently with Service 181 during morning peak hours, with no change to its route.
With the extension to Tengah, there are future planned bus stops for Service 181. These are:
- 2 pairs of bus stops along Bulim Ave
- 1 pair of bus stop along Jurong West Ave 2
- 1 pair of bus stop along Tengah Blvd

181 extension to Tengah have to see when the new roads at Tengah open. Since the LTA has announced that 181 will be extended to Tengah in 2026, without specifying date, it is likely in the 2nd half of 2026, in tandem with JRL construction road reinstatement (Jurong West) and opening (Tengah).
The best decision is to extend 171, and extend 674 peak hours. Pls also give all tengah residents a direct bus link to Airport 1, 2, 3 and 4. I hear that Tengah is a car-free town so it is best to have direct link towards the East as well as north. To make residents happier and enjoy the convenience of having more direct links.
If anyone confused as to why this bus service is classified as a trunk and not feeder:
There are internal plans to extend 181 to Tengah. Still under early planning stages. Junction between Bulim & Tengah not yet fully complete also.
