The A1M has reopened in County Durham after officers closed the road for two hours due to a "police incident".
Emergency services were called shortly after 7.30am on Saturday morning to an incident at junction 58 of the A1 near Darlington. As a result, the road was closed between junctions 57 and 58 (Burtree interchange) in both directions.
It is thought the emergency services were called to help deal with someone in crisis on an overhead bridge.
