Slovenia: A1 between Domžale and Ljubljana back on both carriageways, winter phase from November
On the Štajerska motorway A1, the main route into Ljubljana from Maribor and the Austrian border at Šentilj, the closure of the carriageway towards Ljubljana between Domžale and Zadobrova has been lifted. According to the Slovenian motorway company DARS, traffic towards Ljubljana has been using the renewed carriageway again since the night to Wednesday, October 28, 2026.
This completes an important construction phase, but not the whole project: DARS is adding a third lane between Domžale and Ljubljana. Work continues in 2027, first with a closure of the overtaking lanes to rebuild the central reservation, then the carriageway towards Maribor will be closed and completely reconstructed. The third lane will only open once all work is finished, expected in autumn 2027.
Winter phase from early November
From early November, a new temporary traffic layout applies to the whole section, which DARS calls the winter phase. Work will then mainly take place along the edge of the motorway, so the outermost right-hand lanes or hard shoulders are closed in both directions. Towards Ljubljana the speed limit is 80 km/h, and 60 km/h around the junctions. Towards Maribor the limit is 60 km/h, with traffic running on two temporary lanes, each three metres wide.
Towards Ljubljana, the remaining work mainly involves installing noise barriers. Between Domžale and Sneberje it is due to finish by the end of November, between Sneberje and Zadobrova probably by mid-December. Towards Maribor, the hard shoulder between Zadobrova and Domžale is expected to stay closed all winter.
Šentjakob junction
According to DARS planning, the Šentjakob junction was closed in the direction of Ljubljana from July to October, both exit and entrance, with a diversion via the Sneberje junction. On promet.si, the DARS traffic portal, this closure is no longer listed on October 30. On that day, the portal instead reported a closure of the Šentjakob entrance towards Celje and Maribor.
How to plan your trip
This stretch is one of the busiest sections of the Slovenian motorway network, and traffic jams can occur especially during peak hours and at weekends. DARS publishes current updates on promet.si, and short-notice changes are possible. Important: a vignette is required for motorways in Slovenia — you can find details in our guide to the Slovenia vignette and the traffic rules in Slovenia.
There are also restrictions elsewhere on the A1: we have reported on the construction site near Postojna and the work on the Devina Viaduct between Fram and Slovenska Bistrica.
Slovenia toll at a glance
For cars and motorhomes up to 3.5 t GVW, the digital vignette requirement applies on motorways and expressways. It is a flat fee for a fixed period.
For trucks, buses and motorhomes over 3.5 t GVW, the distance-based toll of the DarsGo system applies instead. Its amount depends on factors such as distance driven, number of axles and emission class. In addition, a separate fee is charged at the Karawanken Tunnel (border with Austria), the only true special toll route in Slovenia, regardless of any other toll product.
