The tunnel maintenance on the Circle Line (CCL), which had affected seven stations, namely Dhoby Ghaut, Bras Basah, Esplanade, Promenade, Nicoll Highway, Marina Bay and Bayfront stations, is expected to be completed on Monday (Jun 26) night.

Train services on the CCL will resume normal operations from Tuesday onwards, over three weeks ahead of schedule, the Land Transport Authority (LTA) announced this afternoon.

LTA said routine inspections had uncovered that a small segment of the CCL tunnel between Promenade and Nicoll Highway stations “has been subject to greater pressure”.

It added that it had “assessed that this poses no safety risks to CCL train operations” and 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”.

CCL train services at seven train stations were originally affected by single platform operations that begin at 9pm daily, except on certain dates, from Jun 11 to Jul 20.

Commuters travelling between seven MRT stations on the CCL were advised to expect longer travel times of up to 30 minutes to facilitate the maintenance works along a tunnel segment.

“We are happy to report that these works are progressing ahead of schedule and will be completed by tonight,” LTA said this afternoon.
