Police say they've identified the person who was found dead on the M5 near Gloucester Services last week.
Following detailed investigative work they believe that the body was that of a 66-year-old woman from Gloucester who was reported missing during the morning of 30 October, a number of hours after the incident was reported.
Her next of kin has been informed.
Officers are not treating the death as suspicious and are compiling a report for the coroner.
They would like to thank everyone who responded to appeals for information and dashcam footage following the incident, and road users for their patience and understanding whilst the initial investigation was under way.
