We received a report of a road traffic collision involving two cars on the B4245 Caldicot Road between Rogiet and Undy at around 11.25am on Thursday 19 March.
The collision involved a silver Peugeot 308 and a red Toyota Yaris.
A 71-year-old woman, who was driving the Yaris, from the Caldicot area has sadly died. She can now be named as Ann Hadwick.
Officers are continuing to investigate the incident and are keen to speak with anyone who may have witnessed the collision and any person travelling along that road at that time that may have dashcam footage.
We are eager to speak to the driver of a white Volkswagen Transporter panel van that was travelling directly behind the Toyota Yaris at the time of the collision as they may have important information that could assist in the enquiry.
Anyone who may have witnessed this incident, or has dashcam footage, can contact Gwent Police on 101, quoting either log reference 2000097295 or 105 19/03/20.
