The digger, which was being used for ongoing roadworks, was taken from the central reservation at Junction 61 near Bowburn around 5pm by two men who were seen loading it onto a trailer and driving off.
The trailer was followed to the Darlington area and pursued by Durham Constabulary officers before it was dumped on the A66.
