The R245 Carrigart Road near Creeslough will be closed from 8am to 5pm today and tomorrow to facilitate resurfacing works.
The works are a continuation of the 2025 road improvement programme and will take place in the townland of Killoughcarron.
A diversion route will be in place via the N56 to Kilmacrennan, the R246 to Milford, and the R245 to Carrigart, with the route operating in both directions.
Donegal County Council says all diversions will be clearly signposted.
