Présentation

• La route départementale D21 (45), ou RD21 (45), est une route départementale du Loiret (45) qui contourne actuellement Saint-Denis-de-l’Hôtel par le Nord. Elle a été mise en service le 5 septembre 2023, remplaçant d’ailleurs en partie la D411.
• À terme, la route contournera aussi Jargeau par l’Ouest pour se terminer sur la D13 au nord de Marcilly-en-Villette, traversant la Loire par un viaduc long de 570 m.
• Le tronçon situé au Sud de la D951 devrait être mis en service fin 2024, tandis que la section centrale devrait l’être en mars 2025.
• Malgré le fait qu’une portion de cette route se situe sur le territoire d’Orléans Métropole, elle reste entièrement gérée par le département.
