Roadworks disrupt traffic in Croatia, Montenegro and Bosnia

In Croatia, the Croatian Auto Club (HAK) reported that traffic generally proceeds without special limits, but warned of localized incidents. A deer was sighted on the A6 Rijeka‑Zagreb motorway between the Čardak and Podvugleš tunnels, and a pedestrian was observed on the A7 near the Učka interchange, prompting speed restrictions to 60 km/h. Additional temporary speed limits of 60 km/h and 50 km/h were applied on sections of the A6 and A7 due to oil spills. Congestion was noted near Zagreb on the A4 and the Zagreb bypass (A3), with lane queues extending up to three kilometres. No maritime traffic problems were reported.

In Montenegro, the national road authority announced extensive construction on major routes, including the M‑6 Tara bridge reconstruction, regional roads R‑29, R‑17, R‑14, R‑30, and the Podgorica‑Božaj corridor. Heavy‑truck traffic (over 3.5 t) is fully prohibited on certain stretches from March 2026 until works finish, while passenger vehicles face alternating‑traffic regimes and time‑based closures. Specific bans are in effect during early‑morning, midday, and evening hours on designated dates throughout 2025‑2026. Restrictions also apply to vehicles over 7.5 t between June 15 2026 and September 15 2026 on the Tara‑1 motorway segment.

In Bosnia and Herzegovina, the BIHAMK agency said driving conditions are good but highlighted temporary measures. Heavy‑truck traffic is banned until 16:00 on the Jajce‑Crna Rijeka road for the "Sveti Ivo" event, with detours via Jajce‑Mrkonjić Grad‑Banja Luka. Explosive‑material transport is prohibited in the Central Bosnia canton after dark. Several highway sections (A‑1 Kakanj‑Lašva, Sarajevo‑Podlugovi, etc.) are closed or rerouted for repair works, with weight limits of 3.5 t on certain main roads. Border crossings are experiencing up to 30‑minute delays due to the EU Entry/Exit System.
