From 22 August 2026, all four lanes on the A5 between the Teningen and Freiburg-Nord junctions will be routed over the carriageway towards Basel. DB is building new bridges there for the freight rail line – expected to last until March 2027.
Quick overview
This report is primarily relevant for rail travelers because it may have concrete effects on planning, connections or infrastructure. The focus is on Deutsche Bahn, freight rail line, Karlsruhe–Basel, A5, construction site, new bridge construction and infrastructure. The key points are summarized compactly below.
Key points
- From 22.08.2026, a new traffic routing applies on the A5 between Teningen and Freiburg-Nord: all four lanes will run over the carriageway towards Basel.
- The changed traffic routing is expected to remain in place until March 2027.
- During this time, DB will build the first half of a new bridge structure over the Feuerbach underneath the carriageway towards Karlsruhe.
- Previously, the lanes had been shifted outwards over 1.3 km from 13.07.2026; this phase ends in mid-September 2026.
- The measure is part of the construction of the new freight rail line between Offenburg, Freiburg and Müllheim (Markgräflerland) in the Karlsruhe–Basel project.
What this means for travelers
In the short term, little usually changes for travelers; in the long term, however, such projects can deliver more stable timetables, better connections and more capacity. During construction phases, diversions and temporary restrictions are possible.
Context
Deutsche Bahn is providing an update on the changed traffic routing on the A5 motorway as part of the construction of the new freight rail line between Offenburg, Freiburg and Müllheim. Between the Teningen and Freiburg-Nord junctions, new bridges are being built over the Feuerbach; this requires a new traffic routing from 22.08.2026 until approximately March 2027.
What to watch now
- Only check specific timetable or construction notices once travel dates are set.
- Allow more generous connection times for international trips.
- Keep an eye on the source and operator information in case dates are still provisional.
