Highways in Greece


The National Roads and Motorways in Greece constitute the main road network of the country. These two types of roads are distinct in terms of their construction specifications. Their main difference is that motorways adhere to higher quality construction standards than National Roads.
For example, a typical motorway in Greece consists of six or four lanes plus an emergency lane, separated by a central barrier. Entrances and exits to the motorways are only provided at grade-separated junctions and there are no traffic lights. Greek motorways are generally organized so that the odd-numbered motorways are of north-south alignment and the even-numbered motorways are of east-west alignment. However, there are many exceptions.
A typical National Road in Greece is usually a single carriageway or limited-access road with at-grade intersections and with one or two traffic lanes for each direction, usually with an emergency lane on each side as well. The designation of some important roads of Greece as "national" was first decided by a 1955 decree, while a minister's decision in 1963 determined the numbering of these roads. In 1998, a survey of the Hellenic Statistical Authority defined some new national roads that were constructed after the 1963 decision.
The naming system of motorways and National Roads is different. For example, "A2" refers to the Egnatia Odos motorway, while "GR-2" refers to National Road 2. All motorways are named by using the capital letter "A", followed by a number. The main motorways of Greece have a single digit number and auxiliary motorways perpendicular to the main ones have a double digit number. Motorways have their own white-on-green signs, while National Roads are designated by white-on-blue signs.
The construction of the Greek motorway network has been, to a large extent, a very complex and demanding project due to the peculiarities of the geomorphology of the areas through which the new roads pass. The Greek mainland is extremely mountainous; the local topography as well as environmental concerns regarding the local flora and fauna played a decisive role in the final route design. In order to overcome these difficulties, the construction of multiple large and expensive technical works, such as tunnels and bridges, was necessary in many cases. Indicatively, the total number of tunnels built along the four Greek major motorways |A1], A2, A5 and A8 motorway is about 150 and their total length is about 200 km.
With a total length of about 2320 km as of 2020, Greece's motorway network is the biggest one in Southeastern Europe and one of the most advanced in Europe.

Motorways

Greece's motorway network has been extensively modernized throughout the 2000s and part of it is still under construction. Most of it was completed by early 2017. There are a total of 10 main routes throughout the Greek mainland and [Crete, from which some feature numerous branches/auxiliary routes, as described in the listing below.

Greek motorways according to ministerial decree of 2015

A1 (Athens - Thessaloniki - Evzonoi)

The A1 motorway, also known as the Aegean Motorway, is the oldest and most important motorway of Greece, connecting the country's largest cities, Athens and Thessaloniki and passing through many important regions of Greece on a south-north direction. Section Chalastra - Evzonoi was constructed earlier as an expressway, with no upgrade planned.
The full length of this motorway is around 553 km or 346 miles, including 14 km or 8.7 miles of shared route with the A2. Note that until recently, the "P" in "PAThE" referred to Patras, but the Patra – Athens section has now become part of the A8, belonging to a different project.
  • The A11 motorway is a branch of the A1, connecting it with the city of Chalcis.
  • The A12 motorway is a planned branch of the A1, connecting it with the city of Volos. Upgrade of the pre-existing section is under way.
  • The A13 motorway is a now cancelled branch of the A1, from Thiva to Elefsina; connecting it with the A6 and serving as a western bypass of Athens Metropolitan Area.

    A2 (Egnatia Odos)

The A2 motorway, also called Egnatia Odos, is a motorway situated in northern Greece, connecting several major cities on the way. It starts at the port of Igoumenitsa and ends at Kipoi border crossing with Turkey.
Part of its length, a section of about 360 km from Evros to Thessaloniki, parallels the ancient Roman Via Egnatia, which ran from modern Durrës in Albania to Thessaloniki and thence to Byzantium. The project has therefore been dubbed a modern Via Egnatia. However, the parallel is not exact; the original Via Egnatia was much longer and its western section, from Thessaloniki to the Adriatic Sea, ran much further north than the modern road.
Specifically, there are auxiliary routes to Albania and Bulgaria, with the main route leading to Turkey. North Macedonia is accessed through the A1, as described above, or via the A27. Another auxiliary route runs close to the Evros river in the prefecture of the same name, reaching a point where Greece's, Turkey's and Bulgaria's borders meet. Some of those auxiliary routes are not yet motorways, but typical 2-lane expressways, although they are of considerably higher quality than other similar expressways in the rest of Greece. The project, was completed in 2009, with the length of the main route being 670 kilometers or 416 miles, making it the longest motorway in Greece.
The A3 motorway, or the Central Greece Motorway is currently under construction. It will link the A1 near Lamia with the A2 near Grevena, and carry the European route E65. Its total length will be.
Construction began in 2009, lasted 2 years and stopped in 2011 due to the financial crisis. At the end of 2013 it was decided to proceed with the immediate construction of the central middle section, Trikala–Xyniada with a length of 80 km, while construction of the northern and southern sections was postponed.
The middle section between Xyniada and Trikala was inaugurated and opened to traffic on December 22, 2017. In October 2018 the European Commission approved the funding for the construction of the southern section, Xyniada - Lamia, which out of the 32,5km, the 14,2 km section from the A1 to Karpenissi I/C is opened to traffic on July 15, 2021, while the rest is expected to be completed by 2024. The construction of the northern section, Trikala–Egnatia Odos junction, has started on November of 2021 with completion due by 2025.

A5 (Ionia Odos)

The A5 motorway, also referred to as the Ionia Odos, is a fully operational motorway since 3 August 2017 when its last section under construction was delivered to traffic. It starts from Ioannina at the A2 interchange, and ends at Rio, in Patras, after crossing the Corinthian Gulf through the Rio-Antirrio bridge. There, it connects to the A8. The northern extension to the Kakavia border is in the planning stages.
The route passes through most of western continental Greece, along the Ionian Sea, hence its name "Ionia Odos". Work on the majority of the highway began in spring 2006 and would span six years, to be completed by 2012. Though, because of economic problems of the constructing companies, all construction works were halted in 2011, but since mid-2013 works on the whole of the 196 km motorway started again. The Antirrion - Ioannina section was completed in August 2017.
The A52 motorway, also known as Ambrakia Odos is a branch of the A5 connecting it with the island of Lefkada and the undersea-tunnel of Aktio, leading to Preveza. This motorway section is expected to serve the popular tourist region around the Ambracian Gulf. At long, the motorway was expected to finish in 2012, having started construction in 2009. Earthworks were largely completed by April 2012 but structures had not commenced as of that time. In mid-2013, works had begun again, but as of December 2016, problems with funding have kept the road largely behind schedule. The section from the Preveza - Aktio tunnel to Vonitsa and the section from Ionia Odos to Loutraki, have been opened to traffic in 2019 and 2022 respectively. The final section from Loutraki to Vonitsa was completed and opened to traffic in 2024.

A6 (Attiki Odos)

The A6 motorway, or Attiki Odos, forms part of the urban motorway network of Athens's metropolitan area. Its full length is and it is also planned to be extended to various directions, bringing its total length to. The Attiki Odos has various auxiliary routes, namely the Aigaleo Ring Road and the Hymettus Ring Road, serving parts of western and eastern Athens respectively; while the 6 km section leading from the main route to the Athens International Airport is numbered as the A64.
The A7 motorway starts from Corinth, at the interchange with the A8 motorway and continues to Kalamata, passing through Tripoli. It replaced the old GR-7 as the main road, with the section between Corinth and Tripoli, constructed between 1984 and 1990 and officially becoming part of the Greek road network in 1992.
The A7 has recently undergone extensive improvement to full motorway standards. As of December 2012, the motorway section between Corinth and Kalamata is fully constructed and operational. Its total length is 205 kilometers or 127 miles.
  • The A71 motorway is a branch of the A7 from Lefktro, connecting it with Sparta. It was opened on 18 April 2016.

    A8 (Olympia Odos)

A8 motorway, also known as the Olympia Odos, is the motorway from Athens to Pyrgos. It begins in Elefsina, at the interchange with the A6 and continues to the A5 interchange near Patras. The Patras - Pyrgos section opened in July 2025. The motorway will in future be extended to Tsakona where it will intersect with the A7.
The Elefsina–Corinth section has been completed to motorway standards, while the Corinth – Patras section begun construction in 2008, and was due to be completed in 2012. After construction works had begun again the whole motorway was completed in 2017. It includes the widening and general reconstruction of the GR-8A along with some new tunnels and bridges.

A90 (Northern Crete motorway)

A90 motorway is a temporary name for a motorway under construction in Crete. It is more widely known as North Road Axis of Crete and is Greece's only motorway that is not on its mainland, but on an island. Certain parts have already been completed, as of summer 2007, such as the bypasses at Heraklion, Rethymno and Chania. In late 2014, the Agios Nikolaos - Kalo Chorio part was opened to traffic. Its full length will be 310 kilometres or 193 miles from Sitia in the east to Kissamos in the west, and it is expected to be completed by the year 2031.

Electronic toll system and interoperability

On April 4, 2018, an international tender was launched by the Greek government for the Εxpression of Ιnterest for the procurement, design and installation of a satellite and electronic toll system in the Greek motorways, using automatic number plate recognition and GNSS technologies. The new system would be the first distance-based pricing model in Greece, replacing the existing toll plazas and charging vehicles depending on the distance covered in the entirety of the country’s motorway network.The project's cost was estimated at about €400 million.
The system would be double; Passenger vehicles' license plates would automatically be captured and identified by traffic cameras upon their entrance and exit from the tolled motorway network with the use of ANPR technology, while professional and heavy vehicles would all carry transponders which would monitor and record their position using satellites. 5 contenders participated in the tender, namely Aκtor SA – Intrakat – Intrasoft Int’l SA- Autostrade Tech S.p.A., Mytilineos – Nusz, Terna – Vinci – Kapsch TrafficCom, OTE – T-Systems International GmbH and STRABAG – SkyToll. In May 2019, the second phase of the tender was completed and two consortiums passed, Aκtor SA – Intrakat – Intrasoft Int’l SA- Autostrade Tech S.p.A. and Mytilineos – Nusz. Finally, a week before the legislative election of July 2019, the then Minister for Infrastructure, Transport and Networks Christos Spirtzis appointed concessionaire the consortium of Aκtor SA – Intrakat – Intrasoft Int’l SA- Autostrade Tech S.p.A., after evaluation of the financial offers.

Cancellation of the first tender

Although the tender for the new system had been strongly disputed by the contestants themselves, the then Minister Ch. Spirtzis of Syriza decided to proceed with it. The concerns regarded the subject of the tender itself, as such a wide implementation does not exist in any developed country, as well as the absence of an agreement for the implementation of such a system. Moreover, existing concession agreements with the private companies managing most of the Greek motorways would have to be amended.
In the autumn of 2019, the tender for the electronic toll system was cancelled by the Council of State following the discovery of several deficiencies and an appeal by the Mytilineos – Nusz consortium, second bidder of the tender, and other participants regarding the bid evaluation procedure, noting that its bid was not preferred although it was lower by €70 million. The tender was officially cancelled at the end of May 2020.

Interoperability

From March 2011, five of the total of seven operating concessionaires of the Greek motorways are part of an interoperable network named "GRITS", which allows drivers to travel along the participating motorways, passing from the electronic toll lanes, using a single transponder.
In October 2019, it was agreed that the remaining two concessionaires, as well as the currently state-owned Egnatia Odos SA, would join the GRITS network. Drivers will therefore be able to travel and pay tolls electronically using a single transponder across the entire Greek motorway network. In the autumn of 2019 technical discussions began between all the companies, testing of the system began in the summer of 2020 and it is expected to become operational in the autumn of 2020.

Current construction projects in Greece

As of 2026, the following are under construction:
This is a list of European routes in Greece. When certain highways that carry European routes are replaced with motorways, the European routes will normally be reassigned to the new motorway: for example, EO7 road used to carry the E65 from Tripoli to Kalamata. When the A7 motorway was completed, the E65 was reassigned to it.
