Two lanes that were closed on the M25 for emergency repairs have now re-opened.
Repairs took place on the Dartford tunnel, from Dartford (A206) to Lakeside (A1306)
The left-hand tunnel is still currently closed and traffic is being diverted via the east tunnel.
On Monday there were long delays after National Highways shut the same tunnel for emergency repairs.
Queues on that occasion stretched back to Swanley.
