Road changes around AMK Hub will begin on 14 November 2026 and are expected to remain until May 2028, after underground obstructions forced Cross Island Line tunnelling works to stop.
The Land Transport Authority (LTA) announced the changes on 16 October to provide space for investigations and recovery works.
The estimated 18-month period may change as work progresses.
What Changes For Motorists And Pedestrians
Along Ang Mo Kio Avenue 3, the eastbound stretch between AMK Hub’s pick-up and drop-off point and Ang Mo Kio Avenue 8 will become a bus-only lane. Westbound traffic lanes will be reduced from three to two.
Drivers can still use the basement car park and the pick-up and drop-off point, but the way vehicles get in and out of the drop-off area will be different.
LTA expects motorists entering the mall during peak periods to face longer queues and an additional 10 to 15 minutes of travel time.
Pedestrians on the eastbound side will be routed through the mall instead, and the crossing is being relocated.
Ground-level access to the overhead bridge on the mall side will close. Pedestrians can access it through AMK Hub’s second floor during mall operating hours.
Bus stops will remain accessible, with barrier-free access maintained.
Underground Anchors Halted Tunnelling
LTA identified the obstructions as ground anchors, steel supports installed underground to hold retaining walls or structures in place.
Workers extracted about 800kg of wire ropes from the tunnelling machine between May and July, replacing 22 damaged cutters.
LTA is investigating the anchors’ origins and assessing the impact on the construction schedule.
In response to CNA’s queries, LTA said the anchors were absent from available records and as-built drawings. Borehole investigations can also miss slender anchors unless they intersect them.
