STRABAG d.o.o., as the leading partner of a consortium, has been awarded the contract to build the final missing section of Slovenia’s 3rd Development Axis (Northern Corridor) – Lot A Velenje. The construction project on the Velenje–Koroška expressway is a crucial link that will improve regional connectivity, relieve existing road networks, enhance traffic safety and shorten travel times between Slovenj Gradec and Velenje.
The contract has a total value of around 194 million euros, with STRABAG holding a 60% share. Commissioned by Slovenia’s national motorway company DARS d.d., the project forms part of a long‑term national infrastructure programme strengthening mobility between the Austrian and Croatian borders. The 3rd Development Axis is also aligned with Slovenia’s broader infrastructure development strategy, which is supported by national investment programmes and EU cohesion policy priorities.

The awarded Lot A – Velenje includes:
- 2.1 km new expressway
- a 552 m two‑lane viaduct
- 1,120 m of cut‑and‑cover tunnels and caissons
- a 231 m railway underpass
- 280 m of temporary deviation of the railway line
- two interchanges (Velenje, Škale)
- 3.9 km of bypass and service roads
- five junctions and five noise barriers
The STRABAG consortium will also carry out extensive work to lay supply lines and regulate the water supply. The construction work will take around 40 months and will start in March 2026. STRABAG can look back on many years of successful cooperation with DARS d.d. For this project, too, the consortium combines extensive regional expertise and capacities to ensure efficient and high-quality execution.
Slovenia continues to invest in the expansion and modernization of its transport infrastructure. Thanks to government funding and development priorities at EU level, the country remains an attractive and stable market for large-scale infrastructure projects. STRABAG has been active in the Slovenian market since 1995. Current flagship projects in Ljubljana include the Emonika project with the tallest office tower in Slovenia and a new university complex for the Faculty of Veterinary Medicine. In Slovenia, STRABAG recently achieved an annual turnover of around 150 million euros and has an order backlog of around 350 million euros.
