The M20 is closing from 9pm today for the second successive night.
This is for London-bound traffic, until 6am tomorrow, and is between Ashford and Maidstone.
It is being done so maintenance work can be carried out.
Like last night the section between Junctions 9 and 8 will be closed while barrier maintenance and carriageway repairs are carried out.
It affects part of the motorway that is under Operation Brock, which sees the coast-bound carriageway closed to regular traffic and uses a contraflow system on the London-bound side.
A Highways England spokesman confirmed that coastbound traffic would still be able to use its side of the contraflow.
All vehicles heading towards London will need to follow a diversion, via the A20.
Motorists and motorcyclists should exit at Junction 9 onto the A20 and re-join the M20 at Junction 8, near Leeds Castle.
A low bridge at Harrietsham, which has a height restriction of 15ft 6in (4.7m), means that over-height vehicles must turn around at Junction 9 and head back on the M20 to Junction 13.
They should then join the A20 towards Dover, before joining the London-bound A2.
