The A16 highway, in the direction of Calais – Dunkerque, is under construction until October 18, 2024. Details. The Nord Interdepartmental Directorate of Roads (DIR Nord) has launched a new construction project in the region as part of its network maintenance program. Until October 18, 2024, work is taking place on the A16 highway, in the direction of Calais – Dunkerque. Disruptions are to be expected, including traffic jams and slowdowns. Let’s take a look at the work program on the A16. The work is located in the direction of Calais towards Dunkerque between interchanges n°46 and n°47 of the A16 highway. “A traffic diversion will be put in place, traffic will flow on one lane in each direction,” the DIR said in a statement. Throughout the construction, the exit ramp from A16 (Boulogne) to A26 is closed to traffic. “The detour involves turning around at interchange n°49 to return to the original destination.” The exit ramp from A16 (Boulogne) to the port of Calais is also closed. “The detour involves turning around at interchange n°49 to return to the original destination.” This is also the case for the entrance ramp from Calais-center/Ardres to Dunkerque. “The detour involves taking the A16 towards Boulogne and turning around at interchange n°41 to return to the A16 towards Dunkerque,” it is emphasized. From Sunday, October 13 to Friday, October 18 at 8:00 p.m., traffic from Boulogne to Dunkerque will be reduced to one lane. The DIR plans to close the entrance ramp from Calais-center/Ardres to Dunkerque and will set up a detour which involves taking the A16 towards Boulogne and turning around at interchange n°41 to return to the A16 towards Dunkerque.
