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

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.

Back to Bus Services
Runtime for this service is just diabolical. 80 minutes? No wonder 146 buses are travelling at snail speed.
115 loadings drop, 53M up
146 should go to Defu Avenue 1
3km only…. So short
remember that it will extend further to serve hougang ave 3
How long more ah
When Hougang st 12 and Hougang ave 13 are completed
Routing looks so cooked up. Another Service 992 lookalike routing for now.
At least 992 has healthy loadings compared to this shit… Should extend to serve 115 routes and withdraw that 115..give that 115 to other bus package in future.
You can never merge any service with 115 unless the route plies from Upp Serangoon Rd northbound. 146 comes from the south, making it impossible to effectively absorb 115
146 will only ply Hg Ave 1 north to loop at Kovan. That is probably it
