Police have confirmed the A45 was shut for more than three hours between Northampton and Wellingborough on Wednesday morning (September 8) over concerns for the welfare of a person near the carriageway.
Officers were alerted to reports from the public of a person between Earls Barton and the Wilby Way roundabout at 4.20am. The road was closed in both directions.
A Northamptonshire Police spokesman said the incident was resolved at around 7.30am and the road reopened after the individual had been safeguarded.
