Présentation

• La route départementale D52 (39), ou RD52 (39), est une courte route départementale du Jura (39) qui relie le Pont de la Thoreigne à Lons-le-Saunier.

Historique

Généralités

• Cette route, d'Orgelet à Lons-le-Saunier, débouchait à l'origine dans cette ville par Montaigu.
• Un nouvel aménagement constitué d'une pente à 13 % permit plus tard d'éviter cette commune et sa terrible descente à 15 %. Ce tracé fut ajouté alors à la liste des annexes de la route en tant que D52^E4.
• Les autres annexes sont:
  • La D52^A et la D52^E2 forment un triangle au sud de Lons pour rejoindre la D678. En effet, la D52 a supplanté cette route à la sortie de Lons en direction de Saint-Laurent-en-Grandvaux, évitant ainsi le délicat passage du Creux de Revigny.
  • Les D52^E1 et D52^E3 n'ont pas pu être localisées.

Aménagements

• Diffuseur de Saint-Maur : 1966.
• Déviation de Montaigu : 1975.

Autour de la route
