Classification of the departmental road network (LIR/LID/DIC/DIB) of Côtes d’Armor

Classification of the departmental road network. The Côtes d’Armor Department adopted in 2016 a new classification of its road network: * Regional Interest Liaisons (LIR): These routes contribute to the accessibility of our Department in addition to the national network.They provide links with neighbouring departments with a high level of service in terms of fluidity. * The Departmental Interest Links (LID): These routes ensure the structuring linkage of the departmental network between the different areas of activity of the Department. They ensure the economic and tourist service of the Department by combining issues of fluidity and tourist service of the territory. * Les Dessertes Inter Communes (DIC)/Dessertes Inter Bourg (DIB): In complementarity with the routes of connections, these two networks ensure the fine service of our territory without the notion of a transit route. This characterisation makes it possible to define a main road network of connecting routes of approximately 1 100 km, and a secondary network of local services of approximately 3 500 km.
