Présentation

• La route départementale D45 (972), ou RD45 (972), est une route départementale de la Martinique (972) située au Nord-Ouest de Fort-de-France reliant les quartiers Clairière à Fontaine Didier.
• De Clairière au rond-point du Viet-Nam Héroïque, cette route constitue un accès à la première ceinture des quartiers situés au Nord-Ouest de l'agglomération. Au-delà de la rocade, elle favorise la desserte des quartiers de Bas-Didier et Didier sur un itinéraire rectiligne.
• Après avoir rencontré la route menant à Desrochers (D55), la D45 se fait plus étroite en direction des quartiers enclavés de Haut-Didier et Morne Coco. Passé le Tunnel de Didier et l'usine d'eau potable éponyme, elle entame une sinueuse et progressive ascension vers les Pitons du Carbet. La route s'achève cependant bien au Sud de ces derniers, en pleine forêt tropicale face à la Fontaine Didier.
• Elle comporte une annexe numérotée D45^A permettant de desservir le Morne Tartenson.
