Warsaw has seen major infrastructural changes over the past few years amidst increased foreign investment, economic growth and EU funding. The city has a much improved infrastructure with new roads, flyovers, bridges, etc.
Warsaw lacks a good ring road system and most traffic goes directly through the city centre, leading to the third highest level of congestion in continental Europe. The city has a direct motorway connection with Łódź, Poznań and ultimately with Berlin.
The city has two international airports: Warsaw Chopin Airport and Warsaw-Modlin Airport, located 35 kilometres away from the city.
The main railway station is Warszawa Centralna serving both domestic traffic to almost every major city in Poland, and international connections. There are also five other major railway stations and a number of smaller suburban stations. Pendolino high-speed trains connect Warsaw, Kraków, Wrocław, Tri-City and the Upper Silesian Metropolitan Area. The regional rail and light rail is operated by Polish State Railways (PKP). There are also some suburban bus lines run by private operators.
Bus service covers the entire city, with approximately 170 routes totalling about 2,603 kilometres, and with some 1,600 vehicles.
Currently, Warsaw trams run 863 cars on over 240 kilometres of tracks. Twenty-odd lines run across the city with additional lines opened on special occasions.
The first section of the Warsaw Metro was opened in 1995 initially with a total of 11 stations. It now has 21 stations running a distance of approximately 23 km. The second line running east-west will be about 31 km. The central section is 6 km long, with seven stations, opened on 8 March 2015.
