The A28 between Canterbury and Ashford will be subject to a series of overnight closures later this month.
Kent County Council is notifying drivers of temporary traffic prohibitions on the road at Godmersham near Chilham.
The work is scheduled to last from Wednesday, May 9 until Wednesday, May 16.
Highways staff will close the road between 8pm and 5am on weeknights.
The authority said: “There will be no direct access between Canterbury and Ashford using the A28 during these closures.”
Phase one of the work will see the A28 closed between the junctions of Bilting Lane and The Street.
Phase two will see the road closed between The Street and Pope Street.
Drivers will have to use alternative routes such as the A251, the A252 and the A2042.
