Deutsche Bahn is building a new freight rail line between Offenburg, Freiburg and Müllheim and is renewing bridges over the A5 for this purpose. From 6 July, there will be a changed traffic layout between the Teningen and Freiburg-Nord interchanges – expected to last until mid-September 2026.
Quick overview
This report is primarily relevant for rail travelers, as it may have concrete effects on planning, connections or infrastructure. The focus is on Deutsche Bahn, Karlsruhe–Basel expansion, A5, freight rail line, construction work, Freiburg, Teningen and rail infrastructure. The key points are summarised concisely below.
Key points
- In the first construction section between Riegel and March, the new tracks run parallel to the A5 motorway, requiring the renewal of numerous bridge structures.
- From 6 July 2026, initial restrictions on the A5 between the Teningen and Freiburg-Nord interchanges.
- From 13 July 2026, lanes in both directions will be shifted outward over 1.3 kilometres, with a speed limit of 80 km/h.
- Crash barriers and vegetation on the median strip will be removed and asphalted; in addition, new bridges over the Feuerbach will be built.
- The traffic layout is expected to remain in place until mid-September 2026, after which further stages will follow with updated information from DB.
What this means for travelers
In the short term, little usually changes for travelers, but in the long term such projects can deliver more stable timetables, better connections and more capacity. During construction phases, diversions and temporary restrictions are possible.
Context
As part of the Karlsruhe–Basel rail project, Deutsche Bahn is building a new freight rail line between Offenburg, Freiburg and Müllheim. The tracks running parallel to the A5 and the bridge renewals necessitate diversions and lane relocations on the motorway. The measure is part of a co-financed EU project.
What to watch now
- Only check specific timetable or construction notices once travel dates are set.
- Allow more generous connection times for international journeys.
- Monitor the source and operator information, as dates may still be provisional.
