The combined value of Poland’s 4000 largest construction projects has has reached PLN 2tn. Of this sum, PLN 360bn represents projects currently under way, while PLN 1.64tn is accounted for by developments in the tendering, planning, or initial concept stage.
While most megaprojects remain in early-phase development, Poland is now entering a period when many of these long-planned undertakings will begin to materialise. Although some delays or plan revisions are to be expected—typical for investments of this scale—their overall impact on the construction market will grow steadily over the coming years.
To better understand the scale and significance of these schemes, we take a closer look at key infrastructure investments already shaping the future of Poland.
Below we present selected projects from the report prepared by our team. The full study is available in our store.
Major infrastructure developments in Poland
Central Communication Port (Port Polska)
The Port Polska in Baranów is the project with the greatest impact on the Polish economy over the next decade. The estimated cost of the entire project is over PLN 131 bn, of which:
- Airport development – PLN 44bn
- Rail infrastructure (Y-line) – approx. PLN 80bn, designed to revolutionise connectivity between Poland’s top metropolitan areas
The new hub will eventually replace Warsaw’s Chopin Airport as the main aviation gateway and emerge as a central transport node for Central and Eastern Europe. Construction is scheduled for 2026-2032.
CPK is actively preparing documentation and establishing cooperation with subcontractors. In 2024, the construction design for the terminal, railway station, and transport interchange was approved. In the same year, approximately 60 tenders were launched with a total value exceeding PLN 8.3bn.
In 2025, the company initiated a competitive dialogue procedure to select the general contractor for the airport's passenger terminal, alongside a separate procedure for the design and construction of the railway tunnel and station, including the platform hall beneath the airport. In June 2026, CPK signed a contract with Budimex to construct deep foundations for the passenger terminal (PLN 119m) and handed the site over to the contractor. The estimated value of these investments exceeds PLN 10bn.
High-speed rail – the Y-line
Poland’s high-speed rail (HSR) initiative envisions a modern network enabling travel speeds of up to 350 km/h. The concept, known as “Poland in 100 Minutes”, aims to dramatically reduce travel times between the country’s key urban centres.
At the heart of this network is the Y-line, linking Warsaw, CPK, Łódź, Wrocław, and Poznań. The project involves major engineering components, such as:
- A 4.6 km tunnel under central Łódź (construction 2026–2029)
- A 9 km tunnel under Warsaw’s Odolany district (completion by 2032)
The Y-line will be delivered in stages:
- Warsaw–Łódź: scheduled completion by 2032
- Connections to Wrocław and Poznań: operational by 2035, completing the western segment of the HSR network
Estimated cost of the 480-km Y-line: PLN 80bn. Preparatory work is already well advanced, with contracts signed for construction of the Łódź tunnel (phases I & II), and environmental approval granted for the Warsaw Zachodnia-CPK section. Applications have been submitted for environmental clearance on the Pleszew-Poznań and Sieradz-Kalisz-Pleszew corridors. In December 2025, CPK announced the first competitive dialogue procedure in Central and Eastern Europe for the construction of a 13-kilometre section of the KDP between Kotowice and the airport junction (part of the Warsaw-Łódź Y line). A few months later, in April 2026, CPK launched the second tender for the high-speed rail route between the airport junction and the Bolimów junction.
