The Communauté d'agglomération du Boulonnais is continuing to roll out its cycling scheme. The Boulevard de la Liane, the main artery of a business park, is a dense traffic lane and poor in development for mild modes. Its situation makes it a strategic passage for any North-South movement on the territory. The development of the project will make it possible to secure and serve the activity area for soft modes. They will also help to clear hard spots (such as crossings in the vicinity of an interchange and an activity area), connect the existing cycling infrastructure in the north and south of the territory allowing for safe cycling continuity.
