This is a non-exhaustive listing of former bus interchanges or terminals that were once part of Singapore's bus system, and decommissioned due to geographical retention or the introduction of new town centres, or creation of consolidated transportation hubs.
Bukit Panjang Bus Interchange was a bus interchange that served Bukit Panjang. It was close to Bukit Panjang MRT/LRT Station. In 2012, the bus interchange was closed to make way to the Bukit Panjang Integrated Transport Hub. The hub is expected for completion in 2017.
Woodlands Bus Interchange was established to serve the developing northern corridor of Singapore in the early-1980s, and was strategically located next to the Woodlands Checkpoint & Customs, the gateway to Johor, Malaysia. The bus interchange was based along Woodlands Centre Road, the former town centre of the then newly created Woodlands New Town. Woodlands had since grew to become one of the most prosperous new towns and her parent GRC, Sembawang GRC, became the largest single GRC in Singapore.
The announcement to build the North-South Line MRT extension and the Woodlands MRT station that was scheduled to complete and open on 10 February 1996, accelerated plans to relocate and develop an entirely new town centre for Woodlands New Town at Woodlands Square, the new regional centre for Woodlands or more precisely, the entire Sembawang GRC. In late-1996, electronic display boards of TIBS buses serving the Woodlands Bus Interchange began to display notices that the TIBS Woodlands' fleet would be moving to the new interchange at Woodlands Square, Singapore's first mass underground bus interchange – Woodlands Regional Bus Interchange, conveniently located under the Woodlands MRT station, and is connected to Causeway Point with escalators. Woodlands Regional Bus Interchange was closed on 12 March 2016 to make way for Thomson-East Coast Line Construction Project.
