Transport in Hungary relies on several main modes, including transport by road, rail, air and water.
Public roads in Romania are ranked according to importance and traffic as follows:
European route E 60 is the second-longest road in the International E-road network and runs 8,200 km (5,100 mi), from Brest, France, to Irkeshtam, Kyrgyzstan.
The road hierarchy categorizes roads according to their functions and capacities. While sources differ on the exact nomenclature, the basic hierarchy comprises freeways, arterials, collectors, and local roads. Generally, the functional hierarchy can more or less correspond to the hierarchy of roads by their owner or administrator.
European route E 75 is part of the International E-road network, which is a series of main roads in Europe.
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, motorway, and expressway. Other similar terms include throughway or thruway and parkway. Some of these may be limited-access highways, although this term can also refer to a class of highways with somewhat less isolation from other traffic.
European route E65 is a north-south Class-A European route that begins in Malmö, Sweden and ends in Chania, Greece. The road is about 4,400 km (2,700 mi) in length.
The M1 motorway is a toll motorway in northwestern Hungary, connecting Budapest to Győr and Vienna. The first section of the motorway opened in the 1970s, reaching the Austrian border at Hegyeshalom in 1996. It follows the route of the old Route 1 one-lane highway.
The M7 motorway is a Hungarian motorway which runs from Budapest towards the Croatian border at Letenye, reaching Székesfehérvár, then Siófok, a town on Lake Balaton, and the city of Nagykanizsa in the southwest of the country.
Controlled-access highways in Hungary are dual carriageways, grade separated with controlled-access, designed for high speeds. The legislation amendments define two types of highways: motorways and expressways.
The M30 motorway is a Hungarian motorway that connects the M3 motorway to the Slovak R4 expressway near the border town of Tornyosnémeti via Miskolc, forming part of European routes E71 and E79. The first section opened to the public in 2002, and reached the border area in October 2021.
European route E 79 is a road part of the International E-road network. It begins in Miskolc, Hungary and ends in Thessaloniki, Greece, also running through Romania and Bulgaria. The road is 1,300 km (810 mi) long.
European route E73 forms part of the United Nations International E-road network, connecting Hungary and eastern Croatia to Bosnia and Herzegovina and the Adriatic Sea in the vicinity of the port of Ploče. This 679-kilometre (422 mi) route is also designated as the Pan-European Corridor Vc, a branch of the fifth Pan-European corridor. The route largely consists of two-lane roads with at-grade intersections, although in the 2000s, about a third of the route was upgraded to motorway standards. The remainder of the route is currently being upgraded in all the countries spanned. The longest part of this corridor goes through Bosnia and Herzegovina and is widely touted as a road instrumental to the development of the country. The road also serves as the shortest connection of the eastern and southern parts of Croatia.
Roads in Serbia are the backbone of its transportation system and an important part of the European road network. The total length of roads in the country is 45,419 km, and they are categorized as "state roads" or "municipal roads". All state roads in Serbia are maintained by the public, nation-wide, road construction company JP Putevi Srbije.
M4 is a Hungarian expressway which will, upon completion, connect Budapest to Oradea and further Romanian cities. The route will travel in Hungary through Cegléd, Szolnok, Karcag, Püspökladány, Berettyóújfalu, and Nagykereki before reaching the Romanian border.
European route E 71 is a north-south Class-A intermediate European road route. It begins in Košice, Slovakia, passes through Budapest in Hungary, Zagreb in Croatia, and ends at Split in Croatia on the Adriatic Sea coast. The total length of the route is 1,016 km (631 mi). The E71 mostly consists of motorways, but considerable sections are either expressways or two-lane roads with at-grade intersections. Nearly all motorway sections of the E71 are tolled, using various toll collection systems including Electronic toll collection (ETC) and ticket systems. Individual segments of the E71 route are shared with several other European routes. The E71 section between Karlovac and Split is inconsistently physically signposted or marked on maps and route planning software. The E71 route has gradually been upgraded from a regular two-lane road to motorway standards since the 1970s; upgrades are still being carried out in some areas.
This article describes the highway systems available in selected countries.
The Zrinski Bridge or Zrínyi Bridge connects the Croatian A4 and the Hungarian M7 motorways, spanning the Mura River. As it also spans Hungarian–Croatian border, a joint border checkpoint is located north of the bridge. The bridge is located between Goričan interchange of the A4 motorway and the M70 motorway interchange of the M7. The bridge is a part of a major north–south transportation corridor in Croatia and Hungary and a part of European routes E65 and E71 as well as the Pan-European corridor Vb.
The M70 motorway is a motorway in Hungary, connecting the M7 motorway to the A5 motorway in Slovenia. The road is 21 km long and has a speed limit of 130 km/h. The last section was completed in 2006. After the opening of the last missing sections of the M7 on August 19, 2008, there is a direct motorway link from Budapest to Slovenia. The expressway originally consisted of two lanes between Letenye and Tornyiszentmiklós interchanges. As a four-lane, full profile motorway, it opened on December 13, 2019. It was built by the Colas Group.
Via Carpathia is a planned transnational highway network connecting Klaipėda in Lithuania with Thessaloniki in Greece. It is currently planned to open in 2025.
