Traffic forecast until Thursday, 16 August 2018

Friday, August 10, 2018 4:06:00 AM

Due to the summer holidays around Europe until the end of August, we expect to have increased traffic on all weekends (from Friday to and including Monday), especially between Austria and Croatia in both directions. Due to Italian collective holidays, we expect to have increased traffic in Istria between Italy and Croatia as well as on the A1 motorway between Italy and Hungary. 

Drivers should expect longer waiting times, especially at border crossings with Croatia at Istria and at the Gruškovje border crossing in Styria. In the event of longer waiting times at Gruškovje, we recommend using the border crossings Zavrč and Središče ob Dravi.

Frequent congestions are to be expected in Upper Carniola at the Karavanke tunnel, in the direction of Austria. Due to increased checks and controls of the Austrian police, waiting times at the border crossings with Austria may also be longer elsewhere (Ljubelj and Šentilj).

On Wednesday, 15 August, there will be a national holiday in Slovenia, Croatia, Austria, Italy, parts of Germany and Switzerland as well as Poland. It will also be the end of the summer holidays in parts of Germany.

On Tuesday, 14 August, and Thursday, 16 August, an increased number of goods vehicles are to be expected on the A1 motorway between Italy and Hungary.

An overview of border crossings with Croatia is accessible on the map at the website
