A352 (France)

A352 (France) is an autoroute-standard north–south spur in the northeastern France region of Grand Est, located in the Bas-Rhin department. It functions as a connector between the urban area of Strasbourg and the radial network toward Metz, Nancy, and the A4 corridor, while serving local towns such as Saverne and industrial zones near Entzheim. The route plays a role in regional mobility, freight distribution, and cross-border traffic with Germany via links toward Kehl and the Rhine River crossings.

Route description

The A352 begins at a grade-separated interchange with the A35 south of central Strasbourg near the neighborhood of Neudorf and the municipal boundary with Schiltigheim. It progresses northwest as an autoroute-standard dual carriageway, skirting the western suburbs of Strasbourg and providing access to the Eurométropole de Strasbourg conurbation, serving junctions that interface with departmental routes toward Entzheim Airport (Strasbourg Airport), the Zénith de Strasbourg arena, and the industrial areas of La Wantzenau and Hoenheim. The alignment traverses the historic Alsatian plain, crossing canals that feed into the Rhine and running parallel in sections to the railway corridor linking Strasbourg and Saverne (part of the classical line toward Metz and Paris-Est). Its northern terminus ties into routes that feed traffic northwest to Saverne and west to the Vosges foothills, including connections that ultimately reach the A4 and long-distance corridors toward Metz, Nancy, Reims, and Paris.

History

Conceived amid postwar growth in the Bas-Rhin and the expansion of the Autoroute network in France during the latter half of the 20th century, the A352 project emerged to relieve congestion on the A35 urban approaches and to improve access to Strasbourg ahead of major events such as sessions of the European Parliament hosted in the city. Planning phases involved regional authorities including the Conseil régional de Grand Est and national bodies such as the former Ministry of Transport; environmental assessments considered impacts on wetlands linked to the Rhine basin and Natura 2000 sites. Construction occurred in stages, aligning with upgrades to the A35 and the development of intermodal freight facilities near Sélestat and Kehl; these works were coordinated with rail modernization projects at Gare de Strasbourg and adjustments to river navigation on the Ill River. The corridor has been influenced by broader European transport initiatives, including trans-European network planning associated with the TEN-T framework and cross-border cooperation with German state authorities in Baden-Württemberg.

Junctions and connections

Junctions along the A352 provide links to major arteries and local nodes: the connection to the A35 integrates traffic toward Basel and Colmar to the south and toward Kehl and Karlsruhe to the north. Interchanges distribute flows to departmental routes such as the D1004 (historic Route Nationale alignments) serving Saverne and the Voie express feeds toward industrial zones and logistics parks. The autoroute interfaces with multimodal hubs including freight terminals that coordinate with the Port autonome de Strasbourg river facilities on the Rhine and with regional airports such as Strasbourg Airport (Entzheim). Local access ramps connect the A352 to municipal roads serving Lingolsheim, La Wantzenau, and Hœnheim, while park-and-ride and bus interchanges link with services to institutions such as the University of Strasbourg and offices used by bodies like the European Court of Human Rights and the European Parliament constituency in Strasbourg.

Traffic and usage

Traffic on the A352 mixes commuter flows for the Eurométropole de Strasbourg, regional freight movements between industrial clusters in Grand Est and logistics nodes, and international traffic crossing the Franco-German border toward Germany. Peak weekday congestion aligns with commuter windows for workers at the Université de Strasbourg, technicians serving the Bas-Rhin industrial parks, and logistics shifts for distribution centers handling goods bound for Île-de-France and the Benelux. Seasonal variation reflects tourist traffic to cultural destinations such as the Cathédrale Notre-Dame de Strasbourg, the Route des Vins d'Alsace, and ski access routes into the Vosges; freight tonnage statistics mirror activity at transshipment points on the Rhine and at rail terminals serving the European TEN-T corridors. Road safety and maintenance reports have prompted targeted resurfacing and signage upgrades coordinated by the Direction Interdépartementale des Routes.

Future developments and projects

Planned developments aim to optimize capacity, reduce environmental impacts, and enhance modal integration. Projects under discussion include junction reconfigurations to improve flows to the A35 and to Strasbourg Airport, noise-mitigation measures in residential zones such as Lingolsheim, and the enhancement of multimodal terminals to better link autoroute freight with rail freight corridors serving Metz and Germany. Regional transport strategies endorsed by the Conseil Départemental du Bas-Rhin and the Eurométropole de Strasbourg consider demand management, electric vehicle charging infrastructure aligned with national policies promoted by the Ministry for the Ecological Transition (France), and cross-border coordination with Baden-Württemberg authorities to harmonize standards on transnational freight routes. Environmental monitoring and compensation schemes continue in cooperation with entities like Agence de l'eau Rhin-Meuse and Natura 2000 program managers to reconcile infrastructure needs with conservation of the Rhine floodplain habitats.
