Présentation

• La route nationale 637, ou RN637, est une ancienne route nationale française qui reliait Pau à Montgaillard, via Lourdes.

Historique

Généralités

• A sa création, en 1933, elle est définie comme la route de Pau à Bagnères-de-Bigorre par Lourdes.
• Elle est issue de la route départementale n° 4 des Basses-Pyrénées, ou RD4 (64), et du chemin vicinal d'intérêt commun n° 28 des Hautes-Pyrénées, ou Ic28 (65) (en tronc commun avec l'Ic16 (65) dans la traversée de Lourdes).
• Le trajet de Montgaillard à Bagnères-de-Bigorre se faisait via la N135.
• Elle fut déclassée en 1973 en D937. Par la suite, un nouveau tracé avec déviations de villages, numéroté en D938, est venu dédoubler l'itinéraire entre Pau et Nay.

Aménagements

• Déviation Ouest de Lourdes : 1975.

Autour de la route

• Pau : Château, Belvédère des Pyrénées, Funiculaire.
• Grottes de Bétharram.
• Lourdes : Sanctuaire, vieille ville.
