Part of the M20 will be closed in both directions for half of the weekend to allow highways bosses to carry out "routine work" on Junction 10a.
Both carriageways will shut at 10pm tomorrow between Junction 9 for Ashford and Junction 11 for Hythe.
They will remain closed until 6am on Monday, meaning drivers will have to find alternative routes throughout Sunday.
How much are this summer's roadworks affecting you?
The closure will be put in place to allow contractors to carry out "routine work" on Junction 10a, which is due to open within months.
They will be putting in a new cantilever sign, installing mastic on the new bridges and carrying out inspection works on the Kingsford Street footbridge.
Contractors will also resurface the motorway between Junctions 9 and 10 during the closure.
The coastbound carriageway will also shut overnight tonight (Friday) from 10pm until 6am tomorrow (Saturday).
It will reopen for the best part of Saturday until it shuts again at 10pm.
Earlier this week, highways bosses reversed plans to permanently close two slip roads at Junction 10, pushing the closures back.
