Service 139 is a trunk route connecting the residential areas of Toa Payoh, St. Michael’s, Boon Keng and Bukit Merah with connections to the city areas of River Valley, Dhoby Ghaut, Little India and Farrer Park. Offering various unique route connections, demand is largely moderate throughout the day. Double-deckers were first added to the fleet in 2011.

The route receives considerable demand between Whampoa and Toa Payoh, as residents of St. Michael’s commute to nearby Toa Payoh Town Centre. The sector has been enhanced with a supplementary bus service, Service 139M, from 14 Sep 2014.
