Présentation

• La route nationale 249, ou RN249, est une route nationale française, élement de la RCEA, qui relie actuellement Nantes (BP) à Bressuire (79).
• Aménagée en voie express à 2x2 voies, la RN249 s'est progressivement substituée à la RN149 voisine, d'où son nom. Elle est achevée en 2014, en absorbant au passage le tracé de l'ancienne RN2249.
