June the 24th, 2025 – Zagreb is set to transform into one giant construction site this summer, with plenty of extensive works planned during the hottest period of the year.
As Poslovni Dnevnik writes, The City of Zagreb is, as has become somewhat the norm, turning into a huge construction site for summer. Roads are currently being repaired, and lighter congestion is expected because work is being carried out across almost all parts of the city. Some of these extensive works will take up to a year to finalise. On Monday, work began on the third level of the Držićeva – Slavonska interchange.
The project is worth around six million euros, and the renovation will take one year. The project includes the complete replacement of fences, the installation of a new asphalt layer, and the renovation of the supporting pillars and steel cladding of the structure. The third level of the interchange will remain out of service for a year, and temporary traffic regulation will be put into function along the rest of the road. These works will also affect public transport, as reported by N1.
During the month of July, these works will also spread to the area of Vukovarska. From July the 7th to the 13th, the southern carriageway of Vukovarska will be closed in the east-west direction, but tram traffic will function normally. These works relate to the replacement of the complex tram switch system in the southwestern part of the intersection, which, once completed, should increase safety and the flow of trams through this traffic junction. During these works, vehicle traffic will be partially restricted, with the northern carriageway of Vukovarska from east to west blocked off.
In the city centre close to Ribnjak park, a 1.5-kilometre-long tram line is being renovated – from Vlaška to Grškovićeva. The works will last until September. In addition to the tracks, the roadway will also be renovated, giving the entire area a new, more modern look. Temporary bus lines will operate during the works. A complete renovation is also planned for Ksaverska. A total of 1,826 metres of tram lines between Ulica Matije Jandrića and the Mihaljevac roundabout will be replaced by the 8th of September.
Zagreb transforming from a bustling capital city into a construction site in summer isn’t new, but the extent of these works is large. It also includes the city’s main artery – Ilica. The western part of Ilica is awaiting the replacement of its currently somewhat dilapidated water supply pipeline. Work on that will be carried out on the section from Mandaličina to Sveti Duh, and the entire stretch will be closed to motor vehicles for the duration of these works. Tram traffic will also be temporarily affected: lines 2, 6 and 11 will only stop running on weekends. The planned completion of the works is scheduled for early September.
By the end of the year, work on the expansion of Sarajevska, which should become the new southern road entrance to Zagreb, should be completed. Following that, the first expansion of the tram network will be completed. This expansion includes a full profile with three traffic lanes running in each direction, a tram line and pedestrian and bike paths on both sides, as well as noise protection, which should significantly relieve traffic towards Novi Zagreb.
Work is also underway along Selska, which is entering the reconstruction phase. The west carriageway in the south direction between Ozaljska and Zagorska is being closed off due to work on a low-pressure gas pipeline and house connections over a length of 1,500 metres. Traffic will be two-way on the east side of the carriageway. The far west is getting a new layer of asphalt, and Aleja Bolonje will be renovated on the northern lanes – from Škorpikova to Prigornica. The works should take about a month to complete.
On Ljubljanska avenija, reconstruction should last six months. In order to mitigate the impact on traffic, Zagreb will provide a temporary road with two lanes heading in each direction. In the eastern part of the city, the replacement of worn-out steel low-pressure gas pipelines with modern polyethylene pipes is also getting started. The works extend from Borongajska, near the former airport, all the way to Savudrijska. After the completion of the gas works, the plan is to totally asphalt the road. These complex works are scheduled to start by the end of June and be completed by September.
Zagreb’s administration has asked for plenty of patience from those using the roads and public transport during this time. Zagreb transforming into a huge construction site as the summer sun hots up and residents escape to the coast is a scene we see annually, but nobody ever seems to be able to get used to the frequent chaos.
