Route History

Service 981 is a largely industrial route, connecting the many industries around Senoko Loop, Senoko Dr, Senoko Rd, Senoko Ave and Admiralty Rd West with transport nodes at Sembawang Town Centre. Operating only on Weekdays and Saturdays, the route plies in a unidirectional fashion, with Senoko-bound trips in the morning and Sembawang-bound trips in the afternoon or evening. (On Saturdays, the return trips are operated in the afternoon rather than the evening.)

Apart from Service 981, services 169 and 856 provide daily bus connections to the industrial areas around Senoko and Admiralty Rd West. High capacity double-deck / articulated buses are not deployed as rigid buses are able to cope with demand levels.

Fare: Charges fares for regular trunk services. See Bus Fares for exact fares.
