Białystok
The city is, and has been for centuries, the main hub of transportation for the Podlaskie Voivodeship and the entire northeastern section of Poland. It is a major city on the European Union roadways and railways to the Baltic Republics and Finland. It is also a main gateway of trade with Belarus due to its proximity to the border and its current and longstanding relationship with Hrodno, Belarus. Passenger trains connect from Suvalki (Poland), Hrodno and Lithuania to Warsaw and the rest of the European passenger network. An extensive public transportation system is provided within the city by three bus services, but no tram or subway exists.
