Route History

Service 21 spans from Central to East, serving many residential areas throughout its route, such as Whampoa, Balestier, Boon Keng, Kallang, Paya Lebar, Eunos, Kaki Bukit, Bedok Reservoir, Tampines and Pasir Ris. Its lengthy route and large coverage makes it an important inter-town route, and as a result, journey time is relatively long for its length.

Introduced in 1992, the route originally ran between Pasir Ris Int and Lorong 1 Geylang Ter before being extended to St. Michael’s in 1993 following the merger with then-Service 4. Service 21 made history on 26 June 2006 as the first wheelchair-accessible bus service in Singapore following the debut of Volvo B9TL CDGEs on the route.

The route has several key sectors offering important connections, such as that between St. Michael’s Estate and Novena MRT, Farrer Park and the Geylang district, as well as that between Eunos MRT and Bedok Reservoir Road. As such, in addition to demand from inter-town connections, the route experiences high demand throughout the day, and relies on  fleet comprising mostly of double-decker buses.

Around Farrer Park, the route plies very different stretches in either direction. Commuters are advised to be aware of the bus stops served.

Service 21 is a wheelchair-accessible bus route (WAB) since 26 Jun 2006. It received additional buses under the Bus Service Enhancement Programme (BSEP) progressively from 2013 onwards.
