The closures form part of a wider programme of maintenance works taking place across the crossing from Saturday, February 14 to Monday, February 16, affecting both the tunnels and the bridge.
The Dartford Crossing, made up of the QEII Bridge and two tunnels, is one of the UK’s busiest routes and a lifeline for thousands of motorists every day.
The temporary closures will bring an unusually quiet spell to this crucial stretch of the M25, which links Kent, Essex and the rest of the South East.
National Highways is urging drivers to check live travel updates before setting off, follow diversions carefully and allow extra time for their journeys during the works.
