Mr Dennis Tan Lip Fong asked the Acting Minister for
a. whether an update can be provided on the progress of (i) Circle Line stage 6 and (ii) Thomson-East Coast Line stage 5 and Downtown Line 3 extension; and
b. whether the Ministry can confirm the specific opening months for these segments following the completion of current tunnel reinforcement and systems integration testing.
Reply by Acting Minister for Transport Jeffrey Siow:
1. The ongoing tunnel strengthening works on the CCL must be completed, before the remaining testing and preparatory works for Circle Line Stage 6 can resume and Circle Line Stage 6 can be open. If the tunnel strengthening works remain on schedule, we can open Circle Line Stage 6 in the first half of 2026.
2. The Thomson-East Coast Line Stage 5 and Downtown Line 3 extension are expected to open in the second half of 2026.
3. More details on specific opening dates and any further service adjustments required to prepare for the opening of these line extensions will be announced when ready.
