Singapore Buses route 109

Service 109 is a service that goes from Serangoon all the way to Changi Village, which is under Foo Chun Ying.

Service 109 is an inter-town route connecting the residential estates of Serangoon, Hougang, Sengkang, Pasir Ris and Changi Village. In addition, it incorporates an express sector between Sengkang East Rd and Pasir Ris Dr 12 along the Tampines Expressway (TPE).

Service 109 compliments Service 89 for the sector between Pasir Ris West and Sengkang MRT. The service benefits from moderate to high demand throughout most of the day due to few duplicating routes along its inter-town sectors.

Double deckers were later introduced in May 2012.
