Bus Service 146 serves new housing estates in Bidadari and along Hougang Street 13, connecting them to the various nearby MRT Stations such as Bartley, Woodleigh & Kovan, 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.
The route was extended to loop at Hougang Street 21 (Kovan Hub), via Hougang Ave 3, Hougang Close, Hougang Ave 1, Tampines Rd and Kovan MRT Station under the Land Transport Authority’s Bus Connectivity Enhancement Programme (BCEP) in December 2025.
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

Heresay there will extend to Hougang Ave 3
no shit dude, it was literally on the goddamn poster 💀
well, at least not as short as 114 leh
Yup, sooner or later – 146 might be a primary for both Woodleigh-Bidadari as well as Hougang South-Neighbourhood 1 BTOs.
Good move to later extend ti woodleigh. They probably do not want to wait for woodleigh ith to open the introduce 146 so thats why it was introduced early
Suggest if they extend this service: Woodleigh to Hougang Ctrl MRT(Loop) via Bidadari Park Area, Bartley MRT, Defu Avenue 1, Hougang Ave 7, 5 and loop at Hougang Central/Avenue 4
Nah it’s more likely to be extended via Hougang St 12,13 and Avenue 1 to serve the upcoming Hougang Olive and Hougang Citrine BTOs. Actually they should just merge the extended 146 with 115.
Merge with 115 and loop at Kovan Hub? Makes a lot of sense, actually.
However, I was thinking it could be extended to Bedok using part of 22 old alignment and 93 current alignment, effectively meaning 93 can be cut back to Serangoon.
Bus Service 146 will be allocated to Serangoon-Eunos Bus Package or Bishan-Toa Payoh Bus Package as it will be operated by SBS Transit.
I believe might be Serangoon-Eunos Bus Package
Yeah that might happen but IT since Woodleigh is nearer to Braddell Bus Park than Hougang Bus Depot
