• Early bus interchanges built by the Housing & Development Board were usually located in the heart of new towns, close to the commercial areas. As many housing estates were built before the 1980s, that was before Singapore had implemented the train system, so there was no plan to connect bus interchanges to Mass Rapid Transit (MRT) stations yet.
• After the Land Transport Authority (LTA) took over the construction and management of bus interchanges, greater emphasis was placed on connecting bus interchanges to MRT stations. For example, the first airconditioned bus interchange was built next to Toa Payoh MRT Station in 2002, while Sengkang Bus Interchange, built in 2003, was connected to both the MRT station and Light Rail Transit (LRT) station.
• In 2013, LTA launched the Walk2Ride programme to build sheltered walkways around bus interchanges. Since 2018, more than 200 kilometres of sheltered walkways connecting MRT stations, LRT stations and bus interchanges have been added.

This morning, the Public Transport Council and students of Chung Cheng High School (Yishun) volunteered their service for a Values-In-Action initiative, to help those in need at the Yishun, Khatib and Ang Mo Kio MRT stations and bus interchanges. (Lianhe Wanbao, 6/3/2019)
