The Central Communication Port (CPK), planned as the Solidarity Transport Hub, will be an integrated transport hub between Warsaw and Łódź, combining air, rail, and road transport. Located on 30 km², Solidarity Airport is expected to handle 40 million passengers annually, becoming a key aviation hub in Central and Eastern Europe. Initially, the airport's development was envisioned as modular, with two parallel runways and plans for additional ones in the future. The project also requires the construction of 1,600 km of new railway lines, enabling fast transport from Warsaw in just 15 minutes. The investment is estimated at PLN 155 billion, with benefits including the creation of 150,000 jobs and increased significance for Polish airlines. Historically, the idea of building a central airport in Poland dates back to the 1970s but has gained particular importance in the context of the approaching capacity limit of Chopin Airport. Interestingly, the airport's architecture has been the subject of work by numerous renowned design firms, resulting in diverse concepts—from an eco-friendly Airport City to modern terminals inspired by Polish heritage. Although the project has many supporters, it also faces opposition from local communities, as evidenced by a referendum in the Baranów municipality, where residents expressed their disapproval. However, 80% of them sold their land for the investment voluntarily, indicating that, despite controversies, the project also has its share of support.
