A pedestrian has died after they were hit by a heavy goods vehicle on a motorway.
The northbound carriageway of the A1(M) has just reopened in the last hour after accident investigators shut off the section between Bowburn and Bradbury following the tragedy.
The incident happened at 1.55am today after the pedestrian on the motorway was killed when they were involved in a collision with the truck around half-a-mile south of junction 61 at Bowburn.
The road was shut from that junction, which meets the A688, and junction 60 at Bradbury, which links up with the A689.
Both sides of the road were closed off in the time after the incident, with the southbound carriageway reopened an hour later.
Police thanked drivers for their patience.
Any witnesses to the incident are requested to contact Durham Police on telephone 101 and quote reference 30 of November 19.
Elsewhere in the region, snow has caused difficulties on the roads.
Durham's officers have said that the A66 westbound and eastbound at Barnard Castle is now moving on both carriageways, however there is still a lot of snow and ice at the location.
Gritters have been out to cover the route, but police have said people should travel through the area if necessary and advised them to take caution.
