A total of 17 East-West Line (EWL) MRT stations and two North-South Line (NSL) MRT stations will be fully closed on Dec. 10 and 17 to allow for extended engineering hours.

In addition, from Dec. 8 to 31, the 17 EWL stations from Tiong Bahru to Tuas Link as well as Bukit Batok and Bukit Gombak stations on the NSL will close earlier on Fridays and Saturdays at 11pm and open later on Saturdays and Sundays at 8am.

The authorities are not ruling out full-day closures in future, and that those closures are likely to take place on Sundays.
