Stage 1 (former Downtown Extension)
On 14 June 2005, Land Transport Authority (LTA) announced the Downtown Extension of the Circle Line to serve the Downtown at Marina Bay area, where an integrated resort (Marina Bay Sands) and Singapore's second botanical garden (Gardens by the Bay) was to be located. The 3.4-kilometre fully underground line was estimated to cost S$1.4 billion. Construction of the extension began in January 2008.
The former Downtown Extension of the Circle Line was subsequently assimilated into the Downtown Line and was revamped as part of Stage 1, a 4.3km, 6 station segment connecting Chinatown to Bugis stations which opened in 22 December 2013.
Stage 2 (former Bukit Timah Line)
Bukit Timah Line was supposedly a 20 km line that would connect the new downtown with the Bukit Panjang, Upper Bukit Timah and Bukit Timah corridor, alleviating the heavy traffic travelling along the sector, but a full route was released. Provisions were provided at Nicoll Highway station which would have seen the line terminating there and interchanging with the Circle Line. However, the Nicoll Highway collapse and subsequent feasibility works deemed the old station unusable.
Now 16.6km long and consisting of 12 stations is scheduled to be completed by 2016. Construction for Stage 2 began on 3 July 2009 with a groundbreaking ceremony at Beauty World Station.
On 24 June 2013, work stopped on the King Albert Park, Sixth Avenue and Tan Kah Kee stations, after Alpine Bau GmbH, the previous main contractor, filed for insolvency on June 19. McConnell Dowell South East Asia (SEA) Private Limited and SK E&C (Singapore) was subsequently contracted to complete the work on the three stations. As a result of the delay, the completion of Downtown Line Stage 2 has been pushed back from December 2015 to the middle of 2016. Subsequently, it was announced that Stage 2 will open in the first quarter of 2016.
On 28 June 2015, Transport Minister Lui Tuck Yew announced that the delay caused by Alpine Bau's insolvency in mid-2013 was "completely resolved" by the authorities and Stage 2 will now be opening on 27 December 2015. 
Stage 3 (former Eastern Region Line)
Stage 3 of the Downtown Line comprises the northern segment of the original Eastern Region Line announced in 2001, a 40-kilometre rectangular loop that would have looped around the Jalan Besar and East Coast areas, intersecting the Circle Line and other current lines along the way and passing through Tampines, Bedok, Marine Parade, MacPherson and Kaki Bukit. On 25 January 2008, it was announced that the northern segment of the original plan from Chinatown to Expo passing through the Jalan Besar area have been merged with the Downtown Line and their station locations and working names for Stage 3 were officially announced on 20 August 2010. It will be 21km long and serve 16 stations. In order to accommodate the construction of an additional station at Jalan Besar, the completion of the segment was pushed to 2017. The finalized names for the Stage 3 stations were announced on 19 August 2011.
Downtown Line Extension
Downtown Line Extension was announced on 15 August 2014, in conjunction with the announcement of the Thomson-East Coast Line. Two stations, Xilin and Sungei Bedok will be added to the Downtown Line, with Sungei Bedok as an interchange station with the Thomson-East Coast Line. It will add an additional 2.2 km to the line with the extension.
