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 discontinued, please refer to this article, which navigates to their dedicated articles.
In this article series, we present the evolution of route changes made to bus services over the decades since the early 1970s. To allow readers to better navigate for the route changes of specific bus service(s), the main article has been divided into a series of smaller-sized articles based on their bus service classification.
