During four nights, workers will test the new removable barrier by installing and removing it.
The M20 will close overnight between junctions seven and nine towards the coast and junctions nine and eight towards London on Friday 11 December for the installation of a movable barrier.
The government website states, “If the M20 reopens at 8am on Saturday, December 12th, the countercurrent will be used in the initial phase.
“The drivers have to follow the different arrangement on the M20 from north of junction 8 (for Hollingbourne / Leeds) to junction 9 (Ashford).
” Trucks entering mainland Europe are driven along the coastal lane with a speed limit of 48 km / h.
“All other traffic is directed to the countercurrent, with two lanes driving in each direction at 80 km / h.”
On Saturday 12 December at 8 p.m., the M20 will close overnight between junctions seven and nine towards the coast and junctions nine and eight towards London in both directions.
They will reopen at 8am on Sunday, December 13th, with the countercurrent open on the final stage.
On the night of Sunday December 12th, the road will be closed between the same intersections and times so that the traffic management can be removed.
The government guidelines state: “If the M20 reopens at 8am on Monday 14 December, the lane towards the coast will be back to normal and all traffic management will be removed.
‘The lane towards London will be open but some traffic management – including the moving barrier – will still be in place.
Speed restrictions apply. The lane towards London will be closed overnight between Junctions 9 and 8 at 8 p.m. on Monday 14 December, with the movable barrier moving to the other side of the hard shoulder. ‘
On Tuesday, December 15, at 8 a.m., the M20 should be back to normal and all three lanes should reach the national speed limit.
