Two drivers were taken to hospital after a van flipped onto its side on a slip road from Cairnhill Circle into the Central Expressway on Monday afternoon, police and the Singapore Civil Defence Force said.
Officers were alerted at about 2 p.m. to a collision involving a car and a van at the slip road leading toward the Seletar Expressway. A 53-year-old man driving the van and a 51-year-old woman driving the car were conscious when paramedics transported them to Tan Tock Seng Hospital.
Scene and road closure
Witness video circulated on messaging groups showed the dark-coloured van resting on its side near the expressway entrance, its driver-side door opening as the man climbed out with help from bystanders. A black car sat partially off the road with its driver door ajar. Debris and a damaged lamp post appeared in photos shared with local media.
The Land Transport Authority said on social media at 2:13 p.m. that the Cairnhill Circle entrance to the CTE was closed after the accident. Police said the car driver is assisting with investigations; they did not immediately release further details on how the vehicles met on the narrow connector used by Orchard-area traffic heading north.
Commuter impact
The closure snarled afternoon traffic between the city centre and northern expressways on a hazy Monday when outdoor workers were already coping with unhealthy air quality. Delivery riders and bus interchanges had been distributing N95 masks through union channels, but motorists on the CTE faced detours rather than filtration issues.
SCDF did not report a fire; the response focused on extrication and medical care. LTA did not provide a reopening time in its initial post, telling motorists to follow traffic advisories on its channels.
Investigation
Police traffic investigators will typically reconstruct speeds and sight lines on slip roads where merging vehicles compete for short acceleration lanes. Insurance and employer liability questions for the van driver may follow once fault findings emerge.
For residents in Cairnhill and Orchard, the crash is a localized disruption rather than a systemic policy fight—unlike ongoing debates over autonomous bus trials or haze subsidies—but it underscores how quickly a single intersection failure can ripple across the island’s expressway spine during peak hours.
Tan Tock Seng Hospital, a major trauma centre north of the city, did not issue a public bulletin on the patients’ conditions, citing patient privacy. Employers whose vans carry tools or catering supplies often face downtime questions after rollovers, because insurance assessors must photograph vehicle positions before clearance.
Union officials who had spent the morning distributing N95 masks to bus workers said the accident was unrelated to haze policy but added to fatigue for crews juggling heat, smoke, and detours. Commuters who rely on the CTE for trips between the CBD and northern housing estates were advised to use real-time map apps through the evening peak.
