Tricity, or Tri-City (Polish: Trójmiasto; Polish pronunciation: [trujˈmʲastɔ], Kashubian: Trzëgard; Kashubian pronunciation: [tʂəɡart]; German: Dreistadt), is an urban area in Pomeranian Voivodeship, Poland, consisting of three contiguous coastal cities in Pomerelia forming a row on the coastline of the Gdańsk Bay, Baltic Sea, namely the cities of Gdańsk, Gdynia, and Sopot, along with other cities and towns in their vicinity.

Tricity Beltway

The Tricity has a well-developed traffic infrastructure and public transport system. Development of the Tricity was smoothed by the construction of the rapid transit rail (SKM) 1951, binding the whole area from Tczew by Gdańsk, Sopot 1953, Gdynia 1956, Reda, Rumia to Wejherowo 1957. In 1975, the Tricity Beltway was constructed.

The Gdańsk Bay Public Transport Metropolitan Union (MZKZG), a body incorporated by the municipalities in the area to act as a common public transport authority, issues tickets valid both for the SKM Rapid Transit Rail, as well as for all or some of the trams and buses in Gdańsk or trolleybuses and buses in Sopot and Gdynia.

Road transport[edit]

The backbone of the Tricity is the inner highway. It starts in Gdańsk and goes through Sopot, Gdynia, Rumia and Reda to Wejherowo. It consists of 2-4 lanes in each direction.

The dual carriageway Tricity Beltway (Obwodnica Trójmiejska) starts in the vicinity of Pruszcz Gdański and goes through the western districts of Gdańsk to Gdynia-Chylonia.

Trolleybus, bus and coach[edit]

The variety and number of public bus lines and coach connections facilitates the travel around the Tricity and surrounding areas. One of the most popular means of transport in the Pomerania province is the public coach. The high number of bus lines covers every quarter of the three cities within the metropolis. In addition to usual buses, the cities of Gdynia and Sopot also operate trolleybuses.

Rail transport[edit]


The city of Gdańsk operates a well-developed tram system.

Tricity Rapid Transit Rail[edit]

The Tricity area is served by the SKM rail network (known in Polish as Szybka Kolej Miejska w Trójmieście or "Tricity Rapid Transit Rail"). It currently provides regular service primarily on two dedicated railways complemented by some of the ordinary railways in the region, both as a commuter rail connecting some of the peripheral towns and villages with each other and with the principal cities of Gdańsk, Gdynia and Sopot, as well as internal rapid transit service within the urban core formed by the three cities. The intervals range from every 6 minutes during peak time on the main common section between Gdańsk and Gdynia to 30 minutes at the farthest ends.

Rapid Transit Rail (the Pomeranian Metropolitan Railway line)

The rapid transit rail network has achieved since its inception in 1951 a unifying effect on the metro area formerly divided by a frontier, by linking the connected localities with a frequent and reliable service. More recently, a pre-war railway destroyed in 1945 by the retreating German army has been reconstructed as the 19.5 km Pomorska Kolej Metropolitalna (Pomeranian Metropolitan Railway) or PKM line, also been operated by the SKM, and put into service in 2015, providing connection of the downtown station of Gdańsk Wrzeszcz Station with the Gdańsk Lech Wałęsa Airport, with further service to the Gdynia Główna Station provided via an earlier existing railway, thus forming a loop connected to the primary SKM line directly at its southern terminus, while the northern terminus is connected indirectly through an earlier existing line. The primary SKM line has been served by overhead-powered electrical multiple units since its inauguration, while the PKM line is currently serviced by oil-powered units, though it is scheduled for imminent electrification.

Regional rail connections and remote rail destinations[edit]

The area is well connected to the rest of the Pomerania region, as well as Poland and the rest of Europe. Polregio network provides a regional rail service connecting the cities and towns of the Pomerania. Gdańsk Główny and Gdynia Główna serve as major rail hubs for the area, with these stations and five others, Gdańsk Wrzeszcz, Gdańsk Oliwa, Sopot, Wejherowo and Rumia offering inter-city services to cities around Poland and in other countries, operated by Polish State Railways under the PKP Intercity branding. Most of the stations that are served by regional and inter-city rail are also part of the above-mentioned SKM network.

Air transport[edit]

Gdańsk Lech Wałęsa Airport

Gdańsk Lech Wałęsa Airport is one of the three busiest Polish international airports. Its position is associated with a well-developed network of domestic and international transport connections provided in response to the growing demand for business and tourist travel.

The Gdańsk Airport is located 10 km from the centre of Gdańsk, about the same distance from the centre of Sopot and 23 km from the centre of Gdynia. The continually expanding road system which connects the airport with the city centres allows drivers to cover the distances in about 15–20 minutes. The close vicinity of the Tri-city by-pass and junctions with state motorways nos. 1, 6 and 7 facilitates access from areas outside the Tri-city. The convenient location of the airport makes it easy for travellers and cargo carriers to transfer from air to road, and also to the railway network and seaports. Gdańsk Lech Wałęsa Airport has its own railway siding which can be used for handling large lots of cargo dispatched by air.

The Gdańsk Airport operates even the biggest planes and allows thousands of tourists to visit the Pomerania province every day. Just in front of the main entrance to the passenger terminal, the visitors can find a bus that will take them to the city centre. There are frequent SKM trains running from the train station in front of the airport to Gdynia, Gdańsk Wrzeszcz, Kartuzy and Kościerzyna. A passenger may also choose to take a taxi.

A failed attempt was undertaken to partially repurpose the Military Gdynia-Kosakowo Airport into a dual-use military and civil one.
