Circle MRT line
The first part opened to the public from Bartley to Marymount on May 28, 2009. When finished, the line will connect all MRT lines, and will allow passengers to bypass the downtown area, so that the City Hall and Raffles Place interchange stations will be less crowded. The second part opened to the public from Bartley to Dhoby Ghaut on April 17, 2010 while the remaining parts will be opened in October 8, 2011. Circle Line Extension (CCLe) had been in operation since 14 January 2012.
