Motorists using the A1 are being warned they could face delays during the rush hour on Thursday morning following a lorry fire near Chester-le-Street.
The fire started on Wednesday evening close to junction 63 on the southbound carriageway.
It is not known how the fire started, but it has since been put out by the fire service.
Drivers will be able to use the second lane of the southbound stretch of the A1, but lane one and the hard shoulder will remain closed between junctions 63 and 62 so that the damage to the road surface from the fire can be assessed.
Durham Police are warning commuters to plan ahead if they need to use that stretch of road on Thursday morning.
