- Tanjong Katong Road South remains closed indefinitely after a sinkhole swallowed a car on 26 July.
- LTA, PUB and BCA are coordinating repair and safety operations.
- Bus routes 36 and 48 diverted; nearby buildings confirmed structurally safe.
- Residents reassured that safety remains top priority.
Tanjong Katong Road South between Mountbatten Road and East Coast Parkway (ECP) will remain closed until further notice as authorities carry out urgent repairs following a sinkhole incident on 26 July 2025.
The Land Transport Authority (LTA) confirmed the closure in a Facebook post, stating that it is working closely with national water agency PUB and the Building and Construction Authority (BCA) to oversee the repair and safety operations.
Sinkhole caused by road collapse
At about 5pm on 26 July, a section of the road collapsed next to a PUB sewer construction worksite near the junction with Mountbatten Road. The collapse created a deep, water-filled sinkhole that swallowed a car.
Videos posted on social media showed migrant workers rescuing a woman from the car using a rope, while others directed traffic and set up cones and barriers to close the road.
The Singapore Civil Defence Force (SCDF) said it was alerted to the incident at about 5:50pm and confirmed that one person was taken to Raffles Hospital for treatment.
Road closures and bus diversions
Due to the ongoing closure, bus services 36 and 48 will be diverted. Both directions will skip all bus stops along the closed section of Tanjong Katong Road South.
Westbound services will also skip stops outside One Amber condominium, Amber Garden, Parkway Parade, and Blocks 72 and 74 Marine Parade Road.
LTA has advised motorists and commuters to plan alternative routes and expect possible delays during peak hours.
Safety checks and repair works
Preliminary assessments by BCA have confirmed that surrounding buildings are structurally unaffected. PUB has also isolated the affected water mains, which were damaged when the sinkhole formed.
According to PUB’s earlier statement, the sinkhole was linked to the failure of a concrete caisson ring within a 16-metre-deep underground sewage shaft under construction. The incident triggered a partial collapse of the adjacent road surface.
Residents express concern
Residents in nearby estates have voiced concerns about the safety of their homes and surrounding roads.
Marine Parade–Braddell Heights GRC MPs Goh Pei Ming and Gho Sze Kee said authorities are prioritising the safety and stability of the area and will continue to update residents as investigations and repairs progress.
What’s next
LTA and PUB said that stabilisation works are ongoing, with the road to reopen only after the ground is deemed fully safe. Repair crews have already filled the sinkhole with liquefied stabilised soil to prevent further collapse.
Motorists are encouraged to check LTA’s TrafficWatch and MyTransport.SG for updates on road conditions and diversions.
