In late August and early September 2026, road safety and traffic management remained critical issues across the Balkans. Heavy summer holiday traffic and religious observances caused significant congestion. In Croatia, the A1 motorway saw queues of up to 14 kilometers following an accident, while Slovenia experienced heavy congestion at the Karavanke and Šentilj border crossings. In Bosnia and Herzegovina, delays occurred at Izačić and Velika Kladuša due to construction and heat, while Serbian toll stations operated at full capacity to manage surges. In Bulgaria, the Road Infrastructure Agency (API) implemented various restrictions and maintenance schedules. To manage peak periods and prevent accidents from improper overtaking, trucks exceeding 12 tonnes faced restrictions on the Trakia, Struma, and Hemus motorways, as well as the I-1 road. Maintenance activities, including roadside vegetation removal and the replacement of toll cameras, led to intermittent lane closures and detours on the Hemus, Trakia, and Struma motorways through late August. Leading into During the Bulgarian Reunification Day holiday on September 6, authorities implemented phased restrictions for heavy vehicles exceeding 12 tonnes to manage surges toward Sofia and mountain resorts. On September 4 and 5, restrictions targeted vehicles exiting Sofia, while on September 7, measures focused on traffic heading toward the capital. In the Simitli area, reversible lanes were used to prioritize travelers heading toward Bansko and Greece via the Struma Motorway. Police in Blagoevgrad warned of potential congestion in the Kresna Gorge. During the holiday weekend, holiday, the Road Police reported 18 serious accidents within a 24-hour period, resulting in two deaths and 22 injuries. ~~To alleviate~~ Significant disruptions included a three-car collision on the ~~surge, authorities suspended major construction~~ Hemus motorway near Elin Pelin and ~~repair works~~ chain collisions on the ~~national road network.
