A39 autoroute
The A39 autoroute is a French controlled-access motorway connecting Dijon and Bourg-en-Bresse via Dole and Lons-le-Saunier, forming a strategic link between A6 and A40. It serves regional hubs such as Poligny and integrates with national corridors toward Lyon, Mulhouse, Besançon, Geneva, and international routes to Switzerland and Italy. Operated by concessionaires including Autoroutes Paris-Rhin-Rhône and managed under French transport planning frameworks, the route balances freight access to industrial zones around Dijon-Longvic Airport and tourism flows to the Jura Mountains and UNESCO-listed sites like Cluny Abbey.
The alignment begins at a junction with A6 autoroute near Dijon then proceeds south-west passing the urban perimeter of Bourgogne towns like Auxonne and Saint-Jean-de-Losne before reaching the Dole interchange. Continuing through the Jura foothills it serves Lons-le-Saunier and Poligny, with connections to regional roads toward Champagnole and Vesoul. The southern terminus connects to A40 autoroute near Bourg-en-Bresse, providing onward links to Lyon and alpine corridors toward Chamonix and Mont Blanc regions. Along its course the motorway crosses river valleys feeding the Saône and the Doubs, and interfaces with rail nodes such as Dijon-Ville station, Dole-Ville station, and freight terminals serving companies like Renault, Peugeot, and Schneider Electric.
Planning traces to national infrastructure strategies in the 1970s and 1980s under ministries led by figures associated with the Plan Barre and later regional development policies influenced by the Schéma directeur d'aménagement et d'urbanisme process. Early proposals involved studies by engineering firms and agencies such as Direction interdépartementale des routes and concession negotiations with Société des Autoroutes Rhône-Alpes predecessors. Construction phases were completed in stages during the 1990s and 2000s amid debates involving local councils in Côte-d'Or, Jura, and Ain; parliamentary discussions in the Assemblée nationale and environmental assessments overseen by Ministry of Ecology, Energy, Sustainable Development and the Sea shaped alignments. Funding blended concession finance from entities like APRR and public contributions tied to European cohesion instruments influenced by European Regional Development Fund priorities.
Major interchanges include the link with A6 autoroute near Dijon, the Dole interchange connecting to national routes toward Besançon and Besançon Franche-Comté TGV station, exits serving Tavaux industrial zones, and the junctions around Lons-le-Saunier with routes to Poligny and Arbois. Southern links connect to A40 autoroute providing access to Mâcon, Geneva, and alpine passages. Designated exit numbers correspond to departmental access points, freight terminals, and park-and-ride sites serving commuters to urban centers such as Dijon and Bourg-en-Bresse. Emergency access coordinates integrate with services like Sapeurs-pompiers de France and highway patrol units tied to Gendarmerie nationale road safety missions.
Rest areas and service plazas along the corridor provide fuel, food, and maintenance services operated by concession partners including TotalEnergies, BP, and franchise chains like Société du Groupement Vivendi food operators and hospitality brands serving motorists, truck drivers, and tourists to destinations such as Château de Savigny and Abbey of Cluny. Facilities include truck parking, electric vehicle charging points promoted by Advenir and regional mobility schemes, and tourist information linking to agencies in Bourgogne-Franche-Comté and Auvergne-Rhône-Alpes. Several service areas offer logistics support for carriers working with firms such as Gefco, GEODIS, and regional SME clusters in Dole technology parks.
Traffic patterns show commuter peaks toward Dijon and seasonal increases tied to tourism to the Jura Mountains and ski resorts accessed via A40 autoroute. Heavy goods vehicle flows serve supply chains for automotive plants in Bourgogne and industrial zones near Dijon. Tolling is administered under concession agreements with toll plazas and electronic systems compatible with national interoperable devices like Télépéage (Liber-t), and payments accepted through providers such as Banque Populaire and Société Générale merchant services. Road safety programs align with campaigns promoted by Sécurité routière and regional police forces, with accident data informing capacity upgrades and enforcement by Direction Interdépartementale des Routes Est.
Engineering works include viaducts, cut-and-cover sections, and earthworks negotiated to reduce impacts on protected landscapes including Natura 2000 sites and regional nature reserves near Rochefort-sur-Nenon. Mitigation measures employed fauna crossings to protect species such as Eurasian lynx and amphibian corridors, and noise abatement walls near urban perimeters of Dijon and Lons-le-Saunier. Environmental assessments referenced EU directives and consultations with bodies like Agence de l'eau Rhône-Méditerranée and local conservatoires such as Conservatoire d'espaces naturels de Bourgogne.
Planned works envisage capacity improvements, interchange remodels to support freight electrification, expanded EV charging infrastructure in partnership with Réseau de Transport d'Électricité initiatives, and smart motorway technologies aligned with pilot programs involving Centre d'études et d'expertise sur les risques, l'environnement, la mobilité et l'aménagement and regional authorities of Bourgogne-Franche-Comté. Discussions include multimodal links to high-speed rail at Besançon Franche-Comté TGV station and freight terminals to enhance interoperability with corridors toward Rotterdam, Genève, and Mediterranean ports like Marseille. Local stakeholders from municipal councils in Dijon, Dole, Lons-le-Saunier, and provincial chambers such as Chambre de commerce et d'industrie de Bourgogne continue to shape timelines and funding.
