Due to national industrial action in France, services to and from Calais will be suspended from 7am UTC on Thursday 19th January.
The Port will still be open, with services to Dunkerque running as normal, but the Port and local road network in and around Dover may be busier than usual.
Travellers are being urged to plan ahead, allowing extra time for their journey and to follow the traffic management systems that are in place to minimise delays.
Calais sailings are expected to resume at approximately 2pm UTC from Dover.
