Planning a drive across Bulgaria
Published · Updated · About 16 minutes of reading
Pick the road class first. The kilometres below are scales for a diary, not a clearance. Route planners disagree by a few kilometres depending on where in Sofia you start.

01
Sofia to Burgas
A1 Trakia · the most continuous motorway day
On the order of 360 to 390 kilometres, depending on the exact ends. Many people allow half a day with one real stop, not a two-hour dash. Summer weekends toward the coast are heavier. Works on Trakia have covered long stretches; a lane closure changes the mood of an otherwise even road.
This is the corridor to read against the network page if you want to see what “continuous” does and does not mean.

02
Sofia to Kapitan Andreevo
A1, then A4 Maritsa · the Turkish border
Around 300 kilometres of road is a fair planning scale to the border area. The queue is not included. Documents, the other country’s checks, and freight controls sit outside any Bulgarian speed limit. A car vignette does not travel with you past the border. A lorry was never on the vignette.
I-8 is the older first-class road on this east–west line. If a closure throws you onto it, the general car limit outside towns is 90, with junctions. Do not keep a motorway pace out of habit.

03
Sofia to Kulata
A3 Struma · Greece, with a gorge still in the way
The distance is modest, often under 200 kilometres on a planner. The Kresna section decides the clock. It is not a finished motorway, whatever a thick line suggests. Budget for a slower, more demanding stretch and for a signed diversion if one is up.
I-1 is the first-class road this motorway replaces in sections. Where you are on I-1, drive it as I-1. The September 2026 roadmap for finishing Struma is a government plan, not pavement.

04
Sofia to Varna
Hemus, then the roads that fill the gap
Road distance is often above 400 kilometres. Clock time is longer than a motorway average because the middle of Hemus is not motorway. Give it most of a day, more in winter, more with a trailer or a laden lorry.
Passes that can appear on the non-motorway options include Shipka and the Troyan pass. They are weather. The winter page is the one to read between 15 November and 1 March, and on any cold week outside that window if you are going over the ridge.

05
Sofia to Kalotina
A6 Europe · Serbia, a short run and a border
This is the short one: on the order of an hour or less of driving from the city, then the border. The final motorway section was reported open in 2026. Crossing time is still not driving time. Do not plan a meeting on the far side as if the barrier were a formality.
Fuel, rest, and the border
Stations along Trakia are part of the ordinary pattern. On a first-class road, and before a pass, fill when you see fuel if you do not know the next hour. A pin on a map is not an open pump.
Private drivers are not under tachograph rules. A pause about every two hours is a habit, not a statute this page is imposing. Commercial drivers have real hour rules; they are summarised on the freight page and belong, in detail, to the operator and the regulation.
A border is a change of rules, insurance evidence, and often of queue. Build it as its own block of time. Night driving on the lesser roads adds animals and unlit junctions. If you can cross the difficult section in daylight, the day is simpler.
A checklist that books nothing
- Licence, registration, insurance that covers Bulgaria.
- Whether the vehicle is under or over 3.5 tonnes, and whether a trailer pushes a car over that line.
- Vignette or distance toll, arranged with the operator, not with bgtol.
- The class of each segment: motorway, express, or ordinary road.
- One place where the motorway is known to stop, if the route has one.
- Tyres if the date is inside 15 November to 1 March.
- Fuel before the pass or the gorge.
- Daylight for the section you trust least.
- 112 stored, and a reflective vest you can reach.
- No assumption that a thick line on a phone is a motorway.
This list does not reserve a hotel, a permit, or a time slot. For the charging column, use the charges guide and then the operator. For the legal ceiling on speed, use the car guide or the motorcycle guide, then the sign.
