Singapore Buses route 3

Service 3 is a trunk service connecting the residential estates of Tampines, Pasir Ris and Punggol. It is also one of the few non-loop routes in Singapore to use a bus interchange as an intermediate stop along its route (Pasir Ris Int). It connects Tampines and Punggol Waterway.

This service also plies different routings in the forward and reverse direction around Tampines Street 21 and 23. Commuters are advised to be aware of the bus stops served.

Service 3 was introduced on 7 April 2002, from Tampines to Pasir Ris Street 71 (Loop), as a loop service with the merger of services 294 and 357 which is due to the manifesto of Tampines GRC. It was being extended to Punggol on 7 December 2003.

Service 3 consists of Volvo B10M Mark IIIs that were replaced by Mercedes-Benz O530 Citaros, and some Scania K230UBs were also deployed on that route, replacing Scania N113CRBs in 2008 and 2009.

Short trip from Tampines to Pasir Ris Street 71 (Loop) still exists under service 3A, which is only available late nights after the last bus 3.
