The route opened on 21 October 2017, with free travel for all DTL stations on the first two days of the line completion.
The line, with an estimated cost of S$12 billion, was considered the government's most ambitious rail project. The cost exceeded those of the Circle Line (at $6.7 billion) and the North East Line (at $4.6 billion). Final costs of building the line may reach an estimated about S$20.7 billion, up more than 70% from the initial estimation, due to sharp rises in construction costs and a number of changes in plans.
In October 2014, it was announced that Stage 2's opening would be pushed back to the first quarter of 2016. This was because one of the main contractors for the DTL2, Alpine Bau (which was building

The station was opened on 28 February 2025, ahead of the original timeline.
Future
On 17 January 2013, plans were announced for a southern extension extending from
Expo to connect with the
Eastern Region line (ERL); the ERL has since been subsumed into the Thomson-East Coast line. The extension was to provide more travel options and enhance connectivity for the residents along the East Coast. The Downtown Line 3 extension (DTL3e) was finalised and announced on 15 August 2014, in conjunction with the announcement of the Thomson–East Coast line.
Two stations,
Xilin MRT station and
Sungei Bedok MRT station, will be added to the Downtown Line, with Sungei Bedok as an interchange station with the Thomson–East Coast line. It will lengthen the line by .
Expected to be completed in the second half of 2026, Stage 3e will connect the current
East–West Line at Expo station and the future TEL at
Sungei Bedok station.
An additional extension to the Downtown Line to
Sungei Kadut station from
Bukit Panjang station was announced on 25 May 2019 by the LTA. The extension is set to cut down travel time to the downtown area by up to 30 minutes for those living in the northwestern area of Singapore. The extension is expected to be completed by the mid-2030s. A study will also be conducted to determine the stops to be added between the Sungei Kadut and the existing Bukit Panjang stations.
On 6 December 2024, it was announced that Stage 3e will commence operation in the second half of 2026.
On 6 January 2025, a extension to the future Sungei Kadut station was announced, including an additional unnamed station between Sungei Kadut station and Bukit Panjang station, slated to begin operation in 2035.
