The new concession has a duration of 50 years. In addition to updating the facilities of the logistics and fishing sectors of the Port of Boulogne-sur-Mer, the concession plans for Société des Ports du Détroit (which provides most of the financing for the project) to extend the Port of Calais, with, by 2021:
- the construction of a new 3-km dyke,
- a 90-hectare basin,
- 44 hectares of new reclaimed land and berths for latest-generation large ferries.
In that way, the concession establishes the Port of Boulogne-sur-Mer’s place as leader in the fields of fishing and fishing-foods, and it reinforces the Port of Calais’ position as leader in cross-Channel passenger and goods traffic.
