Service Modifications Along the Circle Line for Seven Stations

24 May 2023 (Singapore)

Services at seven Circle Line (CCL) stations - Dhoby Ghaut, Bras Basah, Esplanade, Promenade, Nicoll Highway, Marina Bay and Bayfront stations - will be modified over a six-week period to facilitate additional maintenance works along a tunnel segment between Promenade and Nicoll Highway stations.

2.      From 11 June 2023 to 20 July 2023, services at the seven CCL stations will operate from only one platform from 9.00pm daily, except for 16 to 18 June, 24 June, 28 to 29 June, 1 to 2 July, 7 to 8 July, and 14 to 16 July. This will result in longer headways, and commuters will experience additional travel times of up to 30 minutes. For more information on affected dates and adjustments to services, please refer to Annex A.

3.      Routine inspections by LTA and the public transport operators found that a small segment of the CCL tunnel between Promenade and Nicoll Highway stations has been subject to greater pressure. LTA has assessed that this poses no safety risks to CCL train operations. Nonetheless, LTA will carry out precautionary maintenance and strengthening works including installation of steel supports to the tunnel rings to ensure the long-term integrity of the tunnel.  LTA and the operators will continue to regularly monitor tunnels used for rail operations as part of our maintenance regime.

4.      To minimise their inconvenience, commuters are advised to plan their journeys ahead of time and use other rail lines or bus services. Commuters may refer to LTA’s MyTransport.SG mobile app and LTA’s and SMRT’s social media platforms for more details. Posters and station announcements will be rolled out at all CCL MRT stations and selected stations on alternate MRT lines that interchange with CCL stations. Station staff will also be deployed to render assistance at affected stations.
