The Circle Line (CCL) will operate a reduced service on selected days in June and July 2023 between Stadium and Dhoby Ghaut / Marina Bay to facilitate additional maintenance works. On affected days after 9 pm, trains will run a shuttle service between affected stations, at up to 20 mins intervals.
Seven CCL stations are affected by the reduced services, namely Dhoby Ghaut, Bras Basah, Esplanade, Promenade, Nicoll Highway, Marina Bay and Bayfront stations.
According to the Land Transport Authority (LTA), additional engineering hours are needed to conduct preventive maintenance and strengthening works along a tunnel segment between Promenade and Nicoll Highway station. This affected section had been subject to greater pressure and would require the installation of steel supports to the tunnel rings.
Affected commuters are advised to expect longer travel times along the affected sectors or seek alternative travel routes.
Interim Service Pattern
Two shuttle services are deployed to serve the affected stations. Shuttle Service A operates between Dhoby Ghaut and Promenade stations at 15-minute intervals. Shuttle Service B operates between Marina Bay and Stadium stations at 20-minute intervals.
