Bus Service 146 serves new housing estates in Bidadari, connecting them to the nearby Bartley and Woodleigh MRT stations, as well as amenities such as The Woodleigh Mall.
Within Bidadari town, the service serves the new housing estates such as:
- Woodleigh Hillside
- Woodleigh Glen
- Woodleigh Village
- Alkaff Courtview
- Alkaff Oasis
- Alkaff Lakeview
At launch, the route started and ended at pair of bus stops along Bartley Road (start: Aft Upp Paya Lebar Rd; end: Bef Upp Paya Lebar Rd) while looping at Bidadari Park Drive with buses performing layovers at Hougang Bus Depot. With the opening of Woodleigh Integrated Transport Hub on 20 Apr 2025, the route was amended to be a bi-directional service from both Woodleigh Bus Interchange and Bartley Road.
Under the Land Transport Authority’s Bus Connectivity Enhancement Programme (BCEP), the service would be extended to loop at Hougang Street 21 (Kovan Hub) from 14 December 2025, via Hougang Ave 3, Hougang Close, Hougang Ave 1, Tampines Rd and Kovan MRT Station.
Future Plans
With the extension of Service 146 to loop at Hougang St 21 in December 2025, 2 pairs of new bus stops are planned to be served by Service 146 in the future. These are:
- 1 pair along Hougang Close
- 1 pair along Hougang Ave 1

Back to Bus Services
Bartley Road, and the area to hougang Avenue 3 sbstransit should serve towards the area so that some of the residents can know the service route and it just u-turn area of Bartley Road and towards bidader area
When later extend to hougang Avenue 3 that will make almost plenty for rise to the area
Today, 25 Feb 2024, Service 146 is officially in operation!!!
Service 146 is under HGDEP (Serangoon-Eunos Package)
– WLTransit100 (YT)
I feel that it has little to no chance of going to Bishan-Too Payoh Bus Package anymore
BRBP/AMDEP should have intake Woodleigh instead of HGDEP.
HGDEP is so damm full.
OK la I think BRBP will be the best choice.
You expect the BRBP bus to turn one big round?
Sbst wouldn’t do that. It’s wasting fuel
Once Woodleigh ITH presumably open Ss
Though the buses need to layover somewhere… HGDEP is the nearest place available.
~lunartesting23
Thats for the meantime until Woodleigh ITH is opened. Once Woodleigh is opened, it might go to Braddell control
Well we should just wait and see. Who knows 146 might be under BRBP one day
Hmmmmmmmmmmmmm…….., but I think Service 146 should layover at Braddell since it also quite near Woodleigh (for now).
Layover at HGDEP
BRBP too far, buses need to turn one big round
If you care to look at google maps, you will see 146’s ending point at Bartley is super close to HGDEP, just a straight connection, compared to BRBP which is further away.
Sengkang West is almost ready, and currently over 100 HGDEP buses ultilise overnights at Hougang Int, Bus park, Sengkang and Compassvale, so it is still feasible.
146 Will serve Hougang Citrine and Tanjong Tree residences when they are complete. So 146 Route in the future would just be Woodleigh Int -> Hougang Ave 3 (Loop)
164 on the otherhand will be introduced once Baungkok Int opens this year.
True but once Woodleigh opens, it might be under BRBP for good as it is near Braddell
Do you know how packed is Braddell?Full of CDG vehicles and the lot for SBST is only less than 275 buses.Most of the buses will park at Ang Mo Kio which is also full at night.
But HGDEP also packed like crazy… the only other Depot there is is SKWDEP
No more CDGE busses
You expect the BRBP bus to turn one big round?
Sbst wouldn’t do that. It’s wasting fuel
Hgdep got Hg int n sk int for overnight parking
Service should serve towards extend the route of the area so that some of the residents will need to get the bus, and to bidader park area
Just wondering ah, y is everyone arguing abt moving TPY services to Woodleigh in this page? Should discuss about service 146 lah! If argue abt TPY bus move to Woodleigh should go to the Woodleigh ITH page.

should extend this service to loop at Kovan MRT to merge service 115 to 146
I like this idea of 115 merge to 146.
