Motorway 1 () 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 (Egnatia Odos). Note that until recently, the "P" in "PAThE" referred to Patras, but the Patra – Athens section has now become part of the A8 (Olympia Odos) motorway, belonging to a different project.[8][9]

• Motorway 11 () is a branch of the Motorway 1, connecting it with the city of Chalcis.
• Motorway 12 () is a planned branch of the Motorway 1, connecting it with the city of Volos. Upgrade of the pre-existing section is under way.
• Motorway 13 () is a now cancelled branch of the Motorway, from Thiva to Elefsina; connecting it with the Olympia Odos motorway and serving as a western bypass of Athens Metropolitan Area.

A2 Motorway Tunnels between Kozani and Veria.

Motorway 2 (), officially named Egnatia Odos (Egnatia Motorway), 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 (220 mi) from Evros to Thessaloniki, parallels the ancient Roman Via Egnatia, which ran from modern Durrës in Albania to Thessaloniki and thence to Byzantium (now Istanbul, Turkey). The project has therefore been dubbed a modern Via Egnatia (in Greek, Egnatia Odos / Εγνατία Οδός). However, the parallel is not exact; the original Via Egnatia was much longer (1,120 km / 696 miles) 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 (PAThE), as described above, or via Motorway A27 (see below). 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 (including most of the auxiliary routes), was completed in 2009, with the length of the main route being 670 kilometers or 416 miles, making it the longest motorway in Greece.

• Motorway 24 () is a branch of the A2 (Egnatia Odos), referred to as the Thessaloniki – Nea Moudania Motorway or Chalkidiki Motorway, connecting Thessaloniki to Nea Moudania on the Chalkidiki peninsula. As it passes through the eastern periphery of Thessaloniki the A24 becomes part of the Thessaloniki Inner Ring Road (Esoteriki Peripheriaki Odos, Greek: Εσωτερική Περιφερειακή Οδός).
• Motorway 25 () is a branch of the A2 (Egnatia Odos) and lies between Thessaloniki to the Greek–Bulgarian border crossing, via Serres (taking over parts of the GR-12).
• Motorway 27 () is another branch of the A2 (Egnatia Odos), at Kozani which leads towards Ptolemaida and from there to Florina and the border crossing with North Macedonia at Niki. Within 2012 tenders were announced for the construction of the 14 kilometers section from Florina up to the border crossing with North Macedonia. Construction of this section started in 2013, finished in 2015 and it was opened to traffic on 20 May 2016. The Ptolemaida - Florina part is currently an expressway, planned to be upgraded to a motorway.
• Motorway 29 () is a branch of the A2 (Egnatia Odos) motorway, connecting it with the city of Kastoria and the Greek–Albanian border crossing at Krystallopigi.

Motorway 3 (), or the Central Greece Motorway (usually referred to as just E65) is currently under construction. It will lead from Motorway 1 near Lamia to Motorway 2 near Grevena and will carry the European route E65. Its total length will be 174 kilometres (108 mi).[8][9]

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 (Grevena-Trikala) and southern (Xyniada-Lamia) 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 Motorway 1 to Karpenissi I/C is opened to traffic on July 15, 2021, while the rest is underway and is expected to be completed until 2023. The construction of the northern section, Trikala - Egnatia Odos junction, has started on November of 2021.[10]

Motorway 5 (), also referred to as the Ionia Odos (Ionian Motorway), 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 (Egnatia Odos) interchange, and currently ends at Rio, in Patras, after crossing the Corinthian Gulf through the Rio-Antirrio bridge. There, it connects to the A8 motorway (see below).

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.[11][8]

The Patras - Pyrgos section is currently under construction. The motorway will in future be extended to Tsakona (near Meligalas) where it will intersect with the A7 (Moreas Motorway). The full length of the motorway will be 364 km (226 mi) on completion.

• Motorway 52 (), also known as Ambrakia Odos (Amvrakia Motorway) is a branch of the A5 (Ionia Odos) 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 48.6 km (30.2 mi) 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 15 km (9.3 mi) section from the Preveza - Aktio tunnel to Vonitsa and the 17 km (11 mi) section from Ionia Odos to Loutraki (also known as Amfilochia bypass), have been opened to traffic in 2019[12] and 2022[13] respectively. The 16 km (9.9 mi) section from Loutraki to Vonitsa is now expected to be completed by fall of 2023.

Interchange at the Attiki Odos Airport entrance

Motorway 6 (), or Attiki Odos forms part of the urban motorway network of Athens's metropolitan area. Its full length is 65 kilometres (40 mi) and it is also planned to be extended to various directions, bringing its total length to 141 km (88 mi). The Attiki Odos has various auxiliary routes, namely the Aigaleo Beltway () and the Hymettus Beltway (), serving parts of western and eastern Athens respectively; while the 6 km (4 mi) section leading from the main route to the Athens International Airport is numbered as the A62.

• Motorway 62 () is a section of the Attiki Odos which branches off at the end of the main A6 route. It basically serves as a corridor from Attiki Odos and Koropi towards the Athens International Airport.
• Motorway 64 () is a section of the Attiki Odos which branches off the main A6 route. It is referred to as the Hymettus Beltway (A64) (Greek: Περιφερειακή Υμηττού), serving parts of eastern Athens, while it is also expected to be extended further southwards to Vouliagmeni and further eastwards towards Rafina.
• Motorway 65 () is a second auxiliary route that branches off the main A6 route. The A64 section of the Attiki Odos is referred to as the Aigaleo Beltway (A65) (Greek: Περιφερειακή Αιγάλεω) and serves parts of western Athens. A small part of the A65 remains still unconstructed, and it is yet unknown when it will be completed.[8][9]
• Motorway 642 () is a small branch of Attiki Odos which connects Attiki Odos with Hymettus Beltway. It serves as a small detour of the main route and its length is 2 km (1.2 mi).

Moreas Motorway (A7).

Motorway 7 (), known as the Moreas Motorway starts from Corinth, at the interchange with the A8 (Olympia Odos) 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.[8][9]

• Motorway 71 () is a branch of the A7 (Moreas) motorway from Lefktro, connecting it with Sparta. It was opened on 18 April 2016.

Motorway 8 (), referred to as the Olympia Odos, is the motorway from Athens to Patras. It begins in Elefsina, at the interchange with A6 (Attiki Odos) and ends at the A5 (Ionia Odos) interchange in Patras.

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.[8][9]

Motorway 90 () is a temporary name for a motorway under construction in Crete. It is more widely known as North Road Axis of Crete (Greek: Βόρειος Οδικός Άξονας Κρήτης, BOAK) 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 (which also serves as a bypass of Agios Nikolaos) was opened to traffic. Its full length will be 310 kilometres or 193 miles[8][9] and it is expected to be completed by the year 2028.

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 (e-tolls) in the Greek motorways, using automatic number plate recognition (ANPR) 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 (including the currently state-owned Egnatia Motorway).The project's cost was estimated at about €400 million.[14]

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 (GNSS technology). 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.[15] 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.[16] 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.[17]

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.[18][19]

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.[17] The tender was officially cancelled at the end of May 2020.[19]

From March 2011, five (Attiki Odos SA, Aegean Motorway SA, Olympia Odos SA, Moreas SA, Gefyra SA) of the total of seven operating concessionaires of the Greek motorways are part of an interoperable network named "GRITS" (Greek Interoperable Toll Service), which allows drivers to travel along the participating motorways, passing from the electronic toll lanes, using a single transponder.[19][20]

In October 2019, it was agreed that the remaining two concessionaires (Nea Odos SA and Kentriki Odos SA), 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.[19]
