EuroAirport is by far the largest airport in the Upper Rhine region in terms of passenger volume. Here is the trend in passenger numbers for each airport in 2025 (Eurostat data)



Nearby Airports

Although they are not located within the Upper Rhine region, several major European airports are fairly easily accessible to residents of the Rhine catchment area:

  • Zurich Airport (ZRH): Switzerland's largest airport, accessible from the southern Upper Rhine region.
  • Frankfurt Airport (FRA): a major European hub that plays a key role in intercontinental connections.
  • Geneva Airport (GVA): an international airport with a strong diplomatic, economic, and tourism focus.

The car: the most popular mode of transportation


Thanks to a dense road network and numerous border-crossing facilities, the car remains the most widely used mode of transportation in the region today. For example, according to INSEE (the French National Institute of Statistics and Economic Studies), 82% of cross-border workers commute to and from work by car. As shown on the map below, the Upper Rhine region is crossed by several major European transportation routes that play a key role in the transport of people and goods.

In the Upper Rhine region, major north-south highways facilitate trade between Northern Europe, the Rhine Valley, Switzerland, and Italy. East-west routes, meanwhile, connect the three countries of the Upper Rhine region and facilitate both daily commuting and the transport of goods.


Electric Vehicles


The significant influx of electric vehicles into the market has necessitated changes to the infrastructure. For example, more than 2,500 charging stations have been installed in the Upper Rhine region.

Cross the border by car


Long regarded as a natural border, the Rhine is now one of Europe’s major transportation corridors. As a key north-south transportation route, it plays a vital role in freight transport while fostering trade between the regions it traverses.


To make it easier to cross the river, numerous infrastructure projects have been carried out over the years. The 41 bridges across the Rhine provide most of the road crossings between the countries along its banks. In addition, several ferries also allow drivers to cross the river in certain areas.

Border crossings are not limited to the Rhine either. In the north and south of the country, several land routes also allow for smooth travel from one country to another.

Public transportation: An efficient and eco-friendly way to cross borders?


The bus and train networks are closely connected to the major urban centers of the Upper Rhine region. Public transportation is used both for daily travel—particularly commuting—and for longer-distance trips.

The region has a well-developed transportation infrastructure and benefits from active cross-border cooperation. This cooperation has led to the creation of several routes directly connecting France, Germany, and Switzerland.

Rail Infrastructure


The Upper Rhine region has a first-rate interconnected network, structured around major north-south corridors extending on both sides of the Rhine:

  • The German Rheintalbahn, a railroad line running parallel to the Rhine
  • The Strasbourg–Basel Connection


Basel SBB (Switzerland): a key hub in the southern part of the region, serving more than 49 million passengers and visitors annually*, connecting the French and German rail networks to Swiss lines.

* Data from 2025, source: SBB data Portal

Strasbourg Train Station (France): The main hub on the west bank, which handles a record number of passengers and visitors—nearly 29 million per year*.

* Data from 2025, source: data portal SNCF

The train stations in Karlsruhe, Baden-Baden, Offenburg, and Freiburg im Breisgau are located along the Rheintalbahn, the Rhine Valley railway line connecting Basel to Mannheim. Located between the Rhine and the Black Forest, this infrastructure serves as a key north-south corridor on the German side of the Upper Rhine and provides connections to regional, national, and cross-border rail networks.

Mulhouse and Colmar (France): High-traffic intermediate stations serving southern Alsace, with 5.7 million* and 4.97 million annual passengers*, respectively.

Train stations by country


This dataset comes from OpenStreetMap, and the two categories of stations can be defined as follows:

Main station: a station serving a major rail line in the network that generally handles significant passenger or freight traffic.

Secondary station: a station serving a local or minor line.


Germany accounts for nearly half of the 910 stations on the Upper Rhine (430), with France and Switzerland sharing the remainder almost equally (241 and 239).


  • In Switzerland, nearly three out of every four stations are classified as main stations (177 main stations compared with 62 secondary stations): this distribution means that almost every station is a transport hub.


  • On the French side, the situation is the reverse (64 main stations compared with 177 secondary ones), reflecting a hierarchical network centred on a few major hubs.


  • In Germany, the figures lie between those of the other two countries (152 main station compared with 278 secondary ones), and its rail network is centred on the Rheintalbahn.

Regional and cross-border train services



Number of regional and cross-border train lines

Some routes link major urban centres and carry a large number of passengers every day, whilst others serve more local needs.

In fact, a large proportion of the passenger numbers on these routes is linked to the movement of cross-border workers, in particular:

  • TER A01 : Strasbourg - Mulhouse - Bâle
  • RB 25 / TER A11 (Europabahn): Strasbourg → Kehl → Offenburg
  • S5: Steinen → Weil am Rhein

Multimodal transport


In the Upper Rhine region, people rarely use just one mode of transport. Bus routes take passengers to railway stations, where regional trains take over.


Some trams also cross the border, with four different routes:

  • Strasbourg Poteries (FR) – Kehl Rathaus (DE)
  • Gare Saint-Louis (FR) – Basel Biersfelden-Hard (CH)
  • Basel Neuweilerstraße (CH) – Weil am Rhein Bahnhof / Zentrum (DE)
  • Rodersdorf (CH) – Leymen (FR) – Dornach (CH)



The cycle network: cycling in everyday life and for tourism

In large cross-border urban areas, such as Strasbourg and Basel, it is possible to make certain daily journeys between countries entirely by bike. Many travellers also combine cycling and train travel for their journeys.

Thanks to the high-quality cycling infrastructure, it is often even possible to travel safely to the neighbouring country via a cycle path (bridges/footbridges) or by using one of the Rhine ferries.

This map shows all types of border crossings accessible to cyclists and pedestrians.
