The construction of the Belgrade Metro stands as the largest single civil engineering project on the horizon and is one of the primary drivers of future economic growth in the coming years in Serbia. For decades, public transport in Belgrade relied solely on buses, trams, and the city railway (BG Voz). Consequently, the development of a comprehensive underground system is expected to have a transformative effect on commuting patterns and travel times. It is worth noting that Belgrade remains the largest city in Europe without a functional underground metro. While the project faced delays for many years, its commencement is now certain, with preparatory works already well underway.

Strategic infrastructure: impact of the Belgrade metro project
The project represents a large-scale international collaboration between China and France. The Chinese construction giant PowerChina is tasked with tunnel boring, while the renowned French company Alstom will provide the rolling stock and system management. Recent reports from China confirm that massive, custom-made Tunnel Boring Machines (TBMs) for the Belgrade Metro are ready, having undergone factory testing, and are set to be shipped to Serbia this June. Two TBMs have been constructed for the first phase of the project, specifically for Line 1. These machines will start boring from opposite ends of the line to meet halfway – a strategy that will make the construction process highly efficient and significantly faster, though it demands exceptional coordination and project management.
Line 1 of the Belgrade Metro is divided into two phases: Phase 1 spans 15km and includes 15 stations, while Phase 2 is a planned extension of an additional 6km and 5 stations. The majority of Phase 1 will be underground, with 11km consisting of deep tunnels and 2km constructed using the cut-and-cover method; only 2.1km of the line will be above ground. The city’s topography presents a significant challenge as some stations will be remarkably deep and complex, reaching up to 40m below ground level. The system will utilize driverless, autonomous vehicles and digital signaling, ensuring maximum efficiency, safety, and frequency.
The original plan envisioned the construction of Line 2 (21km with 23 stations) beginning two years after Line 1, allowing the two projects to partially overlap. However, at this stage, it is uncertain whether parallel realization will proceed as planned. The pace of other phases will depend on the progress of Phase 1 of Line 1, but financial considerations will remain the major factor affecting the speed of future development.
Nevertheless, with the start of Line 1, Belgrade has embarked on a long and ambitious journey that will define the city’s construction landscape for years to come. Estimates suggest that Line 1 could cost between EUR 3.5 and EUR 3.8 billion,meaning the project’s scale will have a tremendous impact on civil engineering output from 2027 onwards. This is a key infrastructure development aimed at boosting growth against recessionary trends in the EU and an unstable global economic environment. On the other hand, the looming dangers of energy shocks, high inflation, and global financial instability remain significant risks—not only for this project but for Serbia’s entire construction industry and the economy as a whole.
