Road Renovations to Croatia 2026: Current Difficulties and Traffic Jams


Current road renovations on the route from Poland to Croatia: How to avoid traffic jams in 2026?
Planning a trip to the Adriatic? In 2026, several key investments are underway on the main transit routes through the Czech Republic, Austria, and Slovenia. Find out where to expect narrowings and how to plan your journey so you don't lose your vacation stuck in traffic.
Key difficulties on popular routes
The choice of route to Croatia usually depends on the starting point in Poland, but most drivers encounter the same bottlenecks. Here are the most important hotspots this season:
Czech Republic: D1 Motorway and Brno area
The perennial renovation of the D1 motorway between Prague and Brno is entering its final phase of interchange modernization. The biggest traffic jams are currently forming around Brno, where the reconstruction of flyovers forces two-way traffic on one lane. An alternative for those traveling from southern Poland might be the route via Ostrava and Olomouc.
Austria: Tauern Tunnel and A10
Advanced renovation work is underway on the Tauern motorway (A10) tunnels. On holiday weekends in 2026, waiting times for passage can range from 30 to 60 minutes. It is worth considering the route via Vienna and Graz (A2), which is currently much more fluid.
Slovenia: Maribor Interchange and Karawanken Tunnel
The construction of the second tube of the Karawanken Tunnel causes periodic traffic stoppages. Additionally, surface renovations around Maribor towards the Macelj border can slow down traffic on Saturday mornings.
Important for travelers: Remember, renovations are not the only obstacle. Lacking a valid vignette carries the risk of a fine that can exceed the cost of the entire trip. Buy official e-vignettes online:
3 golden tips for a stress-free journey in 2026
- Travel during the week: If you can, avoid traveling on Friday night into Saturday. Saturday is the day of shift changes, when renovations are most noticeable.
- Navigation update: Google Maps and Waze in 2026 are very good at dynamically avoiding "live" traffic jams on motorways.
- Fuel and water reserves: If you get stuck in a jam due to roadworks in full sun, air conditioning and hydration are essential.
Frequently Asked Questions about the route to Croatia
Is the route through Hungary better in case of renovations in Austria?
For residents of eastern and central Poland – definitely yes. The M86 motorway in Hungary is modern, less congested, and allows you to avoid traffic jams near Vienna and renovations in Slovenian Maribor.
Where to check current "live" difficulties?
We recommend the services of national road managers: ASFINAG in Austria and ŘSD in the Czech Republic. They publish real-time maps with marked construction areas.
