# Public transport adjustments during summer works > Live situation record from CLSTR: https://clstr.news/situations/transit-rerouting-due-to-construction > Updated: 2026-08-26T11:46:49.000Z. Sources: 84. Developments: 18. June–August 2026 saw a wave of temporary public‑transport changes across the Balkans as cities carried out road, tram, water‑works and utility upgrades. In Belgrade, road works on Nedeljka Gvozdenovića (8–17 July, then 18 July–7 August) and on Bulevar Kralja Aleksandra (6–12 July) forced detours for dozens of bus lines and the suspension of tram lines 2 and 11 on Karađorđeva Street (21 June–1 September). Looking ahead, Belgrade is preparing for the construction of a new metro station, which will require the demolition of the Staklenac shopping center by the end of the year. This project will also necessitate the temporary relocation of the Bajloni market to Dunavska Street; the planned station is expected to feature a platform at a depth of 33 meters. Zagreb continued its intensive summer programme. Major road closures on Vukovarska (June–Sept) and the Vukovarske–Savska intersection (6 July–31 August) were paired with a €3.8 million water‑pipe replacement and a €1.2 million tram‑turning‑box upgrade. Tram line 5 now terminates at Kvaternikov trg, line 7 is rerouted through New Zagreb, and lines 4, 5, 14 and 17 run altered routes. The city also progressed the €25 million Sarajevska Road expansion and the €1.36 million renovation of the central bus station. Ongoing tramway improvements include a two‑phase, €3 million reconstruction of the Zvonimirova Street corridor, with completion slated for 7 September 2026. Additionally, a €3.1 million initiative for tramway infrastructure upgrades involves replacing damaged concrete elements and paving over a two‑year period, with works potentially scheduled for nights, weekends, and holidays to minimize disruption. In Donji Mihaljevec, the demolition of a historic railway station building commenced on 18 August following several years of delays. In Romania, Cluj‑Napoca rerouted several bus and trolleybus lines from 8 June while a temporary bridge over Someșul Mic was repaired. ## Timeline ### 2026-08-26: Zagreb announces major road and tramway infrastructure projects Zagreb is investing millions in infrastructure, including a 1.5 million euro reconstruction of the Selska-Horvaćanska intersection and a 3.1 million euro project to repair tram tracks citywide. 4 sources. https://clstr.news/cluster/zagreb-announces-major-road-and-tramway-infrastructure-projects ### 2026-08-19: Belgrade and Zagreb initiate major urban infrastructure projects Urban development intensifies in Belgrade and Zagreb, featuring metro station construction in Belgrade and extensive tramway track renovations in Zagreb. 8 sources. https://clstr.news/cluster/zagreb-launches-urban-renovation-and-tramway-repair-projects ### 2026-08-06: Zagreb tramway line on Zvonimirova Street begins major reconstruction Zagreb’s Zvonimirova Street tram line is being rebuilt in two phases, costing €3 million, with work from 15 June to 7 September 2026 to reduce noise and improve reliability. 2 sources. https://clstr.news/cluster/zagreb-tramway-line-on-zvonimirova-street-begins-major-reconstruction ### 2026-07-20: Zagreb Bus Station to Receive €1.36 million Renovation Zagreb’s main bus terminal will spend €1.36 million on structural repairs, fire‑safety upgrades, a new ticketing IT system and automatic sanitation‑barrier installations, with work slated to finish by mid‑2025. 3 sources. https://clstr.news/cluster/zagreb-bus-station-to-receive-136-million-renovation ### 2026-07-19: Bucharest bus lines 101, 382, 100, 203, 205 temporarily rerouted Bucharest reroutes bus lines 101, 382, 100, 203 and 205 due to road works and Aviation Day ceremonies, urging riders to check updated maps. 4 sources. https://clstr.news/cluster/bucharest-bus-lines-101-382-100-203-205-temporarily-rerouted ### 2026-07-16: Zagreb's Sarajevska Road expansion and tram line near completion Zagreb is finishing a €25 million expansion of Sarajevska Road and a new 2.25 km tram line, adding three traffic lanes, pedestrian/cycle paths, eight tram stops and serving about 35 000 residents, with service 18 sources. https://clstr.news/cluster/zagreb-advances-major-road-and-tram-upgrades ### 2026-07-14: Croatia rail and tram services disrupted by July construction July rail works around Dugo Selo cause cancellations and bus replacements;
