A crash which resulted in a large oil spillage led to the A47 being closed through the night. National Highways first reported on the collision at around 2am this morning, with the main road shut off between the A10 and A149 at Lynn and the A1122 at Swaffham. Diversion routes were put in place as police attended the scene, with drivers urged to allow extra time for their journeys. The A47 was subsequently reopened shortly after 3.30am. Drivers were thanked for their patience.
