In a single-line tragedy that closed a vital interchange for hours, the incident near junction 24 of the M4 has become the focus of urgent inquiries and public appeals. The south wales argus has learned that emergency services including Gwent Police, the Welsh Ambulance Service and the Welsh Air Ambulance attended the collision, which involved a blue Audi Q8 and a white Triumph Trident motorbike. The motorcyclist, a 61-year-old man from Newport, was taken to hospital and pronounced dead.
Why this matters now
The collision occurred at around 4: 10 p. m. ET on Thursday, March 19, and prompted immediate road closures that affected the A48 and the M4 sliproad at the Coldra roundabout for several hours. A cordon was maintained while officers from the Roads Policing and Collision Investigation Unit carried out accident investigation work. No arrests have been made, and inquiries remain open as investigators work to determine the full circumstances of the crash.

“Officers were called to a collision near junction 24 of the M4 at around 4. 10pm on Thursday, March 19.

The presence of both road policing specialists and air ambulance crews highlights the scale and seriousness of the emergency response.
south wales argus: appeal for witnesses
Gwent Police is urging anyone who may have witnessed the collision, or who may have dashcam footage, to contact the force quoting log reference 2600085541. Members of the public can make contact online, by calling 101, or by sending a direct message on social media. The appeal aims to collect firsthand accounts and any recordings that could assist the Roads Policing and Collision Investigation Unit as it seeks to establish the full circumstances.
Regional consequences and next steps
The closure of sliproads and a stretch of the A48 for a number of hours disrupted traffic patterns around the Coldra roundabout and required coordination between multiple emergency services. Investigators will review evidence gathered at the scene and any witness material to reconstruct events. Meanwhile, specially trained officers are supporting the deceased man’s family as inquiries continue.
The south wales argus will continue to follow this developing investigation and the outcome of the inquiries. As the community awaits more detail, the pressing question remains: who witnessed the moments leading up to the collision, and what can their accounts reveal about how it unfolded?
