Singapore Buses route 317

Service 317 is a feeder service operating from Serangoon Interchange and looping at Berwick Drive, passing through Yio Chu Kang Road and Serangoon Gardens.

Feeder Service 317 serves within the Serangoon Garden estate, linking the private estate and Serangoon Garden circus with Serangoon Town Centre. The route benefits residents of the low-density private housing estate with bus connections to Serangoon MRT and various amenities at Serangoon Central.

Service 317 was introduced in 1977 by the Singapore Bus Service (SBS) as Service 217 to connect the inner neighbourhoods of Serangoon Gardens with the Serangoon Gardens Ter to replace part of the former routes of trunk services within Serangoon Gardens. It was extended to the new Serangoon Int in 1988 and renumbered Service 317 in 1996 to better reflect its status as a feeder service in Serangoon, which follows the 31x series. It is currently operated by SBS Transit, the successor of the SBS.

Fleet
