North-South Corridor opening pushed back two years due to ground conditions

The North-South Corridor will not open as originally scheduled, with the Land Transport Authority confirming a two-year postponement of the project. The delay stems from unforeseen geological challenges encountered during construction, which have forced engineers to adopt more sophisticated building techniques to ensure structural integrity.

The LTA attributed the setback to ground conditions that proved more difficult than initial surveys had indicated. These subsurface complications require additional engineering solutions and extended timelines to safely execute the project's construction phase.

The corridor remains a critical component of Singapore's long-term transport infrastructure strategy. The revised schedule will allow contractors to implement the necessary modifications without compromising safety or quality standards.

Project stakeholders are being briefed on the updated timeline. The LTA said it continues to work with construction partners to deliver the corridor within the new parameters.
