Tampines to Changi Business Park by Bus — Routes & Times 2026
Two public bus services — Bus 20 and Bus 20A — connect Tampines Bus Interchange directly to Changi Business Park. Both originate from Tampines and terminate inside CBP. Journey time is approximately 30–35 minutes on the bus, with 10–16 minutes waiting time off-peak. Total door-to-door by bus: around 50–55 minutes from the Trilliant.
For most CBP workers, the MRT via Downtown Line is faster (approximately 30 minutes). But the bus is useful when MRT disruptions occur, when your office is on the far side of CBP, or when you prefer a seated journey without transfers.

Door-to-Door Time by Bus vs MRT
| Route | Walk to departure point | Wait | Journey | Walk to office | Total |
|---|---|---|---|---|---|
| Bus 20/20A | 12–14 min to interchange | 10–16 min | 30–35 min | 5–10 min | ~57–75 min |
| DTL (MRT) | 9 min to MRT | 3–5 min | 8 min | 5–12 min | ~25–34 min |
The MRT is significantly faster for most journeys. The bus makes sense if:
- There is an MRT disruption
- You prefer a direct seated ride without walking
- Your CBP building is on the far side of the park (bus drops you closer)
- You are travelling off-peak and the wait time is short
