The Marina Line was eventually merged with a planned LRT line that goes from Paya Lebar to Buona Vista via Serangoon and Bishan to form Circle Line Stage 3 on 20 January 2003, and subsequently Circle Line Stage 4 and 5 on 12 December 2003 when Stage 4 was extended from Buona Vista to World Trade Centre to close up the link and to provide connectivity from the west to Sentosa, becoming the Circle Line. On 8 August 2001, SMRT won the bid and was appointed the operator of the Circle Line. Names for the stations for the first three stages of the Circle line were finalised on July 2005 after the Land Transport Authority (LTA) conducted a public consultation exercise on the naming of stations. In November 2005, the names of the stations in Stages 4 and 5 were finalised.
