The Circle Line (CCL) which is set to fully complete from 2010 onwards, will cut travelling time and allow commuters to bypass busy interchanges like City Hall and Raffles Place.

Costing $6.7 billion, the CCL will be a fully underground orbital line linking all radial lines leading to the city. The line will interchange with the North-South Line, East-West Line and North East Line.

The CCL will be 33.3 km long with 29 stations. Starting from the Dhoby Ghaut station, it will run through some of the busiest corridors in the city and end at HarbourFront station on the North East Line.

Other than bringing forward Circle Line Stage 3 that connects Bishan station on the North-South Line and Serangoon station on the NEL to mid 2009, we will also open more stations on the Circle Line such as the Thomson and West Coast Stations. This will enhance the reach and connectivity of the Circle Line, and allow many more people to benefit from the MRT. To enhance the accessibility of the Marina Bay area to the rest of the island, LTA will also build and open the Marina Bay station as part of the CCL extension beyond Bayfront station in 2012.

Using the CCL, commuters will be able to bypass City Hall or Raffles Place stations. This way, they can trim travelling time and avoid transfers at the busy major interchanges.

Similarly, those travelling from Bishan to Buona Vista will soon be able to reach their destinations faster as they no longer need to transfer across different rail lines.

As the line runs through some of the busiest roads in Singapore, its stations are located underground so as to free up land for other uses. In carrying out construction works, we need to divert traffic through the affected areas. Where possible, there will be lane for lane replacement.

Traffic diversions aside, the construction of the line poses other challenges. For example, engineers face soft soil conditions at the future Millenia and Nicoll Highway stations. They also have to be cautious when boring tunnels under the Kallang Basin.

Other challenges include the interface of tunnels with the Kallang Paya Lebar Expressway tunnel, the Deep Tunnel Sewerage System and PowerGrid's cable near the Upper Paya Lebar/ Airport Road junction. Our engineers have to ensure that the various works are well co-ordinated.
