What’s New on Bulgarian Motorways in 2026
Bulgarian motorways are going through another period of modernization and expansion in 2026. The country continues extending its main routes, while also dealing with heavy traffic around Sofia, unfinished sections of key corridors, and a growing number of vehicles heading toward the Greek and Turkish coasts.
For drivers, the most important fact is that 2026 brings several specific changes that may affect both trip planning and driving itself.
Hemus Motorway:
New Sections and Ongoing Construction
The largest motorway project in Bulgaria remains the Hemus Motorway (A2), which is intended to connect Sofia with Varna. Some new sections have been opened in recent months, while intensive construction continues on others.
In 2026, progress is expected mainly in the central part of the route, where construction had been moving more slowly due to difficult terrain and administrative issues. Despite this, it is still not possible to drive the entire route on a continuous motorway, and several sections still require drivers to leave the motorway.
The Bulgarian government continues to describe the completion of the Hemus Motorway as one of the country’s main infrastructure priorities.
Bulgaria Has Adopted the Euro
One of the biggest changes in 2026 is Bulgaria’s entry into the eurozone. The euro is gradually replacing the Bulgarian lev, and the change also affects drivers.
At fuel stations, rest areas, and when paying for services, prices are displayed in euros, while some systems temporarily still show the previous currency as well.
For foreign drivers, this simplifies travel through multiple Balkan countries, as there is no longer a need to exchange local currency.
Sofia Struggles with Traffic Congestion
The area around Sofia remains one of the most problematic parts of Bulgaria’s road network in 2026. The number of vehicles has been increasing for years, and some parts of the ring road and access routes are no longer sufficient in terms of capacity.
Several sections are therefore undergoing modernization and repairs, which should improve the situation in the long term, but currently cause frequent restrictions and slower traffic.
When driving through Sofia, it is therefore worth monitoring live traffic conditions almost in real time.
Towards Greece and Turkey:
Stronger Season Than Before
The year 2026 has brought another increase in traffic heading toward the Greek coast and the Turkish border. The number of vehicles during the summer months has increased again, and some border crossings are experiencing long waiting times.
This mainly affects the following routes:
Sofia → Kulata → Greece
Sofia → Plovdiv → Kapitan Andreevo → Turkey
These are the routes where the longest traffic jams in the country occur during the holiday season.
More Repairs and Surface Modernization
In 2026, a larger number of repairs on older motorway sections continues, especially on routes built many years ago. Bulgaria is trying to improve road surface quality and safety features, but this also means more traffic restrictions than before.
Drivers therefore more frequently encounter:
- Narrowed lanes
- Reduced speed limits
- Temporary traffic restrictions
On some routes, journeys may be slower specifically because of ongoing reconstruction works.
Truck Traffic Continues to Grow
Bulgaria remains one of the main connections between Europe and Asia, which is even more noticeable in 2026 due to the increasing volume of international transport.
As a result, there is a very high share of truck traffic on major routes, especially:
- Toward the Turkish border
- Around Sofia
- On international corridors through Plovdiv
In the event of an accident or restriction, traffic slows down quickly and queues can build up within a short time.
What to Watch Out for When Driving in 2026
When traveling through Bulgaria, it is worth remembering that road conditions can change quickly. A modern motorway can turn into a repaired or slower section within just a few kilometers.
