Présentation

• La route nationale 490, ou RN490, est une ancienne route nationale française qui a connu deux affectations.

Historique

Généralités

• À sa création, en 1933, elle est définie comme la route de Lapalisse à Marcigny.
• Dans l'Allier, elle est issue du chemin de grande communication n° 20, ou Gc20 (03), en tronc commun avec le Gc15 (03) dans la traversée de Montaiguët-en-Forez. Dans la Loire, elle est issue du chemin de grande communication n° 8, ou Gc8 (42), anciennement RD12 (42) jusqu'en 1889. En Saône-et-Loire, elle est issue du chemin de grande communication n° 75, ou Gc75 (71), anciennement RD13 (71) jusqu'en 1855.  
• La liaison de Chambilly à Marcigny était assurée par la N489.
• Elle est déclassée en 1973 en D990 sauf le court passage dans la Loire qui devient D490.
• La D990 fut ensuite déviée au Sud de Lapalisse à la fin du XX^e siècle, l'ancien tracé devenant quant à lui D990^A.
• De 1978 à 1993, le numéro a été réattribué au Boulevard National à Nanterre, en tant que route de Nanterre N190 à Nanterre N186. Cet axe faisait partie de la RN190 de 1950 à 1967. Il est désormais déclassé en D990.
