Singapore’s public bus services have been operating for many decades since the 1960s and underwent numerous rationalisation exercises to reduce duplication between different modes of public transport and provide better connectivity across the island. While many bus services had been discontinued due to low passenger demand and rationalisation exercises after the opening of new MRT lines, other bus services have survived for over 5 decades since the 1971 Bus Reorganisation.

For bus services that were withdrawn, please refer to the Defunct Bus Services Directory, which navigates to dedicated articles for former route information of defunct bus services.

For easier navigation for the historical route information of individual bus services, the table below provides the specific links to the historical route table for each operational bus service. Bus services are listed in order of their introduction date, from the oldest to newest bus service.
