Poland’s flagship new airport which is part of Port Polska has cleared another planning hurdle, with the Mazovian Voivode issuing a location decision for the rail and road junction on the eastern side of the site. The decision carries immediate enforceability, allowing Centralny Port Komunikacyjny (CPK) — the company delivering the Port Polska investment programme — to apply for construction permits for the junction and its supporting infrastructure, and it defines the next tranche of land to be designated as the investment area.
The Eastern Junction will combine two elements: a rail component and a road component. The rail works will connect sections of three railway lines — Lines No. 5, 85 and 88 — together with supporting infrastructure, linking the airport’s railway station to both existing and newly planned lines. The road works involve building new roads and reconstructing or, in places, demolishing existing ones, to keep traffic flowing safely, provide access for railway maintenance, serve passenger facilities, yards and freight-handling points, and preserve the continuity of the local road network.
Where the junction sits — and the land secured so far
The investment lies in the Mazowieckie Voivodeship, within Grodzisk County, across the municipalities of Baranów and Grodzisk Mazowiecki. The area covered by the Eastern Junction location decision totals 212 hectares, of which 85.2 hectares — nearly 40 per cent — have already been acquired under CPK’s Voluntary Property Acquisition Programme.
The junction forms an integral part of High-Speed Rail Line No. 85, which will link the airport with Warsaw and Łódź and whose design work has drawn financial support from the European Union. CPK says the infrastructure will, at every stage, meet the requirements for dual-use infrastructure, enabling both civilian and military use. The decision follows an earlier milestone in January 2025, when the Voivode issued the location decision for the airport itself together with transport infrastructure on its western side — a 2,585-hectare investment across the municipalities of Baranów, Teresin and Wiskitki, granted immediate enforceability in December 2024.
Background: the airport at the heart of Port Polska
Port Polska is CPK’s strategic programme to create an integrated national transport system spanning air, rail and road. At its centre is a greenfield airport being built roughly 40 km west of Warsaw, between the capital and Łódź — billed as the largest greenfield airport project in Europe and the largest hub in Central and Eastern Europe. It is designed to handle around 34 million passengers a year in its first phase, with a flexible, modular design allowing expansion toward 44 million as demand grows.
The terminal and interchange are being designed by a consortium led by Foster + Partners and Buro Happold, with the overall airport-and-rail programme costed at roughly PLN 131 billion (about €30 billion). Construction is scheduled to begin in 2026, with the airport opening before the end of 2032 — timed to coincide with the launch of the first Warsaw–Łódź section of the high-speed rail network. The hub is conceived around rail-air integration, with an underground railway station beneath the terminal and an expectation that a large share of passengers will arrive by train rather than road. Once open, CPK is set to replace Warsaw Chopin as Poland’s primary international gateway.
