Historique

Généralités

Dans l'Ardèche (07)

• La D51 (07) est issue de la route départementale n° 29, ou RD29 (07), créée par l'ordonnance du 21 mai 1837 et décrite comme la route allant de Saint-Ambroix (Gard) à Villefort (Lozère).

Dans le Gard (30)

• À sa création, par l'ordonnance du 28 septembre 1821, la route départementale n° 21, ou RD21 (30), est décrite comme étant la route de Barjac à Villefort (Lozère). Elle s'embranche avec la route départementale n° 14, à Saint-Jean-de-Maruéjols, passant par Saint-Victor-de-Malcap, Saint-Ambroix, Meyrannes, Peyremales, le Chailard, etc, etc, et venant se réunir à la route royale n° 106, près de Vielvic, à la limite des départements du Gard et de la Lozère.
• Les ordonnances du 27 novembre 1850 et du 17 mars 1858 confirment la RD21 (30) étant la route de Barjac à Villefort (Lozère), par Saint-Ambroix.
• En 1891, elle devient le chemin vicinal de grande communication n° 51, ou Gc51 (30) avant d'être incorporée dans la voirie nationale dès 1932 en RN579 de Saint-Jean-de-Maruéjols à la limite départementale de l'Ardèche (07). Suite à la réforme de 1938, elle est classée en tant que chemin départemental n° 51 (30).

Dans la Lozère (48)

• La D51 (48) est issue de la route départementale n° 23, ou RD23 (48), classée par le décret du 08 mai 1861 et décrite comme étant la route allant de Villefort à Barjac (Gard). Cet axe fait partie de plusieurs délaissés de la route impériale n° 106 figurant sur le plan du 09 août 1858. En 1881, elle devient le chemin vicinal de grande communication n° 23, ou Gc23 (48), avant de devenir le Gc51 (48) quelques temps après.
