Major road works on the A16 between Calais and Dunkirk could impact Eurotunnel, DFDS P&O and MyFerryLink customers up until the end of September.
The A16 motorway between Calais and Dunkirk is being resurfaced in both directions up until the end of September.
From 18-29 August the eastbound carriageway Marck to St Folquin, junction 49-51, will be shut. Traffic will be contraflowed with just one lane open in each direction for the 14km stretch.
From 15-26 September the same will happen in reverse for the westbound carriageway. See below for a map, and the official leaflet.
In theory this will only affect drivers heading east from Calais towards the Belgian border but the fear is queuing traffic will back up past the junction for the A26 Paris road.
For this reason, Eurotunnel is advising customers to divert via the A16 to Boulogne then N42 to the A26 at junction 3. This advice surely stands for P&O and MyFerryLink Dover-Calais customers too.
Similarly, DFDS Dunkirk-Dover passengers may be delayed getting into port by backlogs westbound in which case be prepared to divert through Dunkirk itself.

Update 20 August: for the first two days the delays were minimal, a maximum fifteen minutes in each direction. However, from Wednesday 20 August, the road works seem to have started in earnest. We’ll keep a log here of how delays develop.
Update 22 August: delays have started to increase but, apart from brief major build ups, daytime delays are yet to consistently beat 20 minutes.
Update 25 August: delays of up to 35mins in each direction over busy weekend for Calais and Dunkirk.
Update 27 August: with just two days until the eastbound carriageway is set to reopen significant queues have yet to be seen. More next month.
