The Croatian Automobile Club has reported the conclusion of the investigation at the A1 motorway near the Brezik tunnel, but a four-kilometer queue is still moving slowly towards Zagreb. Meanwhile, the Zagreb bypass is experiencing a ten-kilometer traffic jam.
A ten-kilometer queue on the Zagreb bypass-this is, according to the Croatian Automobile Club's report from Tuesday, August 11, 2026, the most drastic consequence of traffic accidents that have paralyzed key Croatian roads, and the weather forecast for Tuesday does not promise any relief.
On the A1 motorway, between the Perušić and Otočac interchanges in the direction of Zagreb, traffic is still moving slowly even after the investigation concluded-drivers are stuck in a queue about four kilometers long that has formed in the area of the Brezik tunnel. The situation is further complicated by intermittent traffic stops in the nearby Plasina tunnel, which are carried out for safety reasons and extend travel time towards the capital.
The A3 motorway hasn't fared any better. A traffic accident on the section between the Buzin and Zagreb zapad interchanges, specifically at kilometer 16+100 in the direction of Bregana, has reduced driving to just one lane-and the result is the aforementioned ten-kilometer traffic jam.
Drivers are also encountering slowdowns on the A2 Zagreb-Macelj motorway, where between Krapina and Đurmanec in the direction of Macelj, as well as from Trakošćan towards Đurmanec in the direction of Zagreb, traffic is flowing in only one lane. On the Solin-Klis expressway (DC1), after the Jamani viaduct in the direction of Solin, a broken-down truck has forced a speed limit of 40 kilometers per hour.
HAK also warns of long-term roadworks that will disrupt traffic flow for months. Drainage rehabilitation on the A3 between the Popovača and Kutina interchanges in the direction of Lipovac will last until September 1, while works between the Sveta Nedelja and Zagreb zapad interchanges-where the carriageway in the direction of Lipovac is completely closed-are scheduled until October 3; on these sections, traffic is moving in both directions using narrowed lanes, and congestion is particularly likely during morning and afternoon hours as well as on weekends.
The traffic forecast for Tuesday, August 12, brings no relief. Due to strong bura winds on the Adriatic, restrictions are possible for certain vehicle groups, especially on the Adriatic Highway in the Podvelebit area, and morning and afternoon hours will bring congestion on city roads and bypasses-likely queues are expected on the Zagreb (A3) and Rijeka (A7) bypasses, as well as on the A2 motorway near the Zagreb zapad interchange. Due to stormy winds, difficulties in maritime traffic are also possible, and at certain border crossings, drivers can expect longer waits.
HAK recommends extra caution on wet and slippery roads in parts of Istria and the wider Rijeka area, urging drivers to maintain a safe distance and form an emergency corridor in case of congestion. Increased traffic on roads towards the coast, with occasional slowdowns in tunnel zones, rest areas, and toll booths, completes the picture of a day where patience behind the wheel will be just as important as fuel in the tank.
