The Corridor IV is one of the Pan-European transport corridors. [1] It runs between Dresden/Nuremberg in Germany and Thessaloniki (Greece) / Constanța (Romania) / Istanbul (Turkey). The corridor follows the route: Dresden / Nuremberg – Prague – Vienna – Bratislava – Győr – Budapest – Arad – Bucharest – Constanța / Craiova – Sofia – Pernik - Thessaloniki or Plovdiv – Istanbul.
The corridor is the shortest land connection between Greece and Central Europe completely on EU territory. It bypasses the countries of former Yugoslavia and the former Brotherhood and Unity Highway (now part of Pan-European Corridor X).
The Vidin–Calafat Bridge across Danube river is one important part of the route. It is one of only two bridges connecting Romania and Bulgaria.
Transportation infrastructure in Romania is the property of the state, and is administered by the Ministry of Transport and Infrastructure, Constructions and Tourism, except when operated as a concession, in which case the concessions are made by the Ministry of Administration and Interior.
Constanța, historically known as Tomis or Tomi, is a port city in the Dobruja historical region of Romania. As the country's fourth largest city and principal port on the Black Sea coast, Constanța is the capital of Constanța County. It is also the oldest continuously inhabited city in the region, founded around 600 BC, and among the oldest in Europe.
Calafat is a city in Dolj County, southern Romania, in the region of Oltenia. It lies on the river Danube, opposite the Bulgarian city of Vidin, to which it is linked by the Calafat-Vidin Bridge, opened in 2013. After the destruction of the bridges of late antiquity, for centuries Calafat was connected with the southern bank of the Danube by boat, and later by ferryboat.
Călărași, the capital of Călărași County in the Muntenia region, is situated in south-east Romania, on the banks of the Danube's Borcea branch, at about 12 kilometres from the Bulgarian border and 125 kilometres from Bucharest. It is one of six Romanian county seats lying on the Danube river.
The Trans-European Transport Network (TEN-T) is a planned network of roads, railways, airports and water infrastructure in the European Union. The TEN-T network is part of a wider system of Trans-European Networks (TENs), including a telecommunications network (eTEN) and a proposed energy network. The European Commission adopted the first action plans on trans-European networks in 1990.
Eastern European Time (EET) is one of the names of UTC+02:00 time zone, 2 hours ahead of Coordinated Universal Time. The zone uses daylight saving time, so that it uses UTC+03:00 during the summer.
The A2 motorway, also known as The Motorway of the Sun, is a motorway in Romania which links Bucharest with Constanța, a city-port on the shore of the Black Sea, where it merges after an interchange into the A4 motorway. It is 206 km long, and has been operational on its entire length since November 2012.
Sirkeci railway station, listed on maps as Istanbul railway station, is a railway terminal in Istanbul, Turkey. The terminal is located in Sirkeci, on the tip of Istanbul's historic peninsula, right next to the Golden Horn and just northwest of Gülhane Park and the Topkapı Palace. Sirkeci Terminal on the European side of the Bosporus strait, along with Haydarpaşa Terminal on the Asian side, are Istanbul's two intercity and commuter railway terminals. Built in 1890 by the Oriental Railway as the eastern terminus of the world-famous Orient Express that once operated between Paris and Istanbul in the period between 1883 and 2009, Sirkeci Terminal has become a symbol of the city. As of 19 March 2013, service to the station was indefinitely suspended due to the rehabilitation of the existing line between Kazlıçeşme and Halkalı for the new Marmaray commuter rail line. On 29 October 2013, a new underground station was opened to the public and is serviced by Marmaray trains travelling across the Bosphorus. Station reopened on 26 February 2024 as part of T6 Sirkeci–Kazlıçeşme Tramway Line / U3 Sirkeci–Kazlıçeşme Rail Line. Sirkeci Terminal has a total of 4 platforms with 7 tracks. Formerly, commuter trains to Halkalı would depart from tracks 2, 3 and 4; while regional trains to Kapıkule, Edirne and Uzunköprü, along with international trains to Bucharest, Sofia and Belgrade would depart from tracks 1 and 5.
East Thrace or eastern Thrace, also known as Turkish Thrace or European Turkey, is the part of Turkey that is geographically a part of Southeast Europe. It accounts for 3.03% of Turkey's land area and 15% of its population. The largest city is Istanbul, which straddles the Bosporus between Europe and Asia. East Thrace is of historic importance as it is next to a major sea trade corridor and constitutes what remains of the once-vast Ottoman region of Rumelia. It is currently also of specific geostrategic importance because the sea corridor, which includes two narrow straits, provides access to the Mediterranean Sea from the Black Sea for the navies of five countries: Russia, Ukraine, Romania, Bulgaria, and Georgia. The region also serves as a future connector of existing Turkish, Bulgarian, and Greek high-speed rail networks. Due to the guest worker agreement with Turkey and Germany, some Turks in Germany originally come from Eastern Thrace, mostly from the Kırklareli Province.
The Port of Constanța is located in Constanța, Romania, on the western coast of the Black Sea, 179 nautical miles (332 km) from the Bosphorus Strait and 85 nmi (157 km) from the Sulina Branch, through which the Danube river flows into the sea. It covers 3,926 ha, of which 1,313 ha is land and the rest, 2,613 ha is water. The two breakwaters located northwards and southwards shelter the port, creating the safest conditions for port activities. The present length of the north breakwater is 8,344 m (5.185 mi) and the south breakwater is 5,560 m (3.45 mi). The Port of Constanța is the largest on the Black Sea and the 17th largest in Europe.
The Corridor X is one of the pan-European corridors. It runs between Salzburg in Austria and Thessaloniki in Greece. The corridor passes through Austria, Slovenia, Croatia, Serbia, North Macedonia, and Greece. It has four branches: Xa, Xb, Xc, and Xd.
The Trans-European conventional rail network, together with the Trans-European high-speed rail network, make up the Trans-European Rail network, which in turn is one of a number of the European Union's Trans-European transport networks (TEN-T). It was defined by the Council Directive 2001/16/EC of 19 March 2001.
The Děčín–Dresden railway, also called the Elbe Valley Railway is an electrified main line in Saxony and the Czech Republic. Formerly called the Saxon-Bohemian State Railway, the line is part of the Dresden to Prague route and is one of Europe's most important trunk routes (Magistralen). It runs along the Elbe Valley from Děčín via Bad Schandau and Pirna to Dresden. The first section of the line was opened in 1848 and is one of the oldest lines in Germany.
The A4 motorway is a motorway in Romania that serves as a bypass for the city of Constanța, between Ovidiu and the Port of Constanța, connecting with the A2 motorway via an interchange southwest of the city. It is 22 km long and is planned to be extended to approximately 60 kilometers, stretching further south to the Bulgarian border south of Mangalia, along the western Black Sea coast. The motorway is part of an extension of the Pan-European Corridor IV, that will be connecting with the Bulgarian city of Varna.
Highways in Bulgaria are dual carriageways, grade separated with controlled-access, designed for high speeds. In 2012, legislation amendments defined two types of highways: motorways and expressways. The main differences are that motorways have emergency lanes and the maximum allowed speed limit is 140 km/h (87 mph), while expressways do not and the speed limit is 120 km/h (75 mph). As of October 2023, a total of 879,1 kilometers of motorways are in service.
The Vidin-Botevgrad expressway is a planned expressway in Bulgaria, that will link the A2 Hemus motorway with Vidin and the New Europe Bridge, at the Danube border crossing to Romania. The expressway shall provide grade-separated dual carriageway with two lanes in each direction and it shall replace or supersede the existing I-1 road.
The Budapest–Belgrade–Skopje–Athens railway, a China-CEE hallmark project (2014) of Beijing’s Belt and Road initiative, is a planned railroad international connection in Central and Southeast Europe – between Budapest (Hungary), Belgrade (Serbia), Skopje, Athens and its China-run port of Piraeus (Greece). Planned speed is up to 200 km/h (120 mph) depending on the sections: 160 km/h (99 mph) on the Hungarian section between Budapest and Serbia, 200 km/h (120 mph) between the Hungarian border and Belgrade and on most of the Belgrade-Niš section, while the current line between Thessaloniki and Athens is 200 km/h (120 mph) with upgrades to 160 km/h (99 mph) ongoing. The Chinese planners do not comment on the other tracks' realizable speeds. Originally, they spoke of up to 300 km/h (190 mph) throughout.
The Alexandroupolis–Svilengrad railway is a 178.5 kilometres (110.9 mi) long railway connecting the port of Alexandroupolis in Eastern Macedonia and Thrace, Greece with Svilengrad in Bulgaria, via the village of Ormenio.
