The A3, known as the Portsmouth Road or London Road in sections, is a major road connecting the City of London and Portsmouth passing close to Kingston upon Thames, Guildford, Haslemere and Petersfield. For much of its 67-mile (108 km) length, it is classified as a trunk road and therefore managed by National Highways. Almost all of the road has been built to dual carriageway standards or wider. Apart from bypass sections in London, the road travels in a southwest direction and, after Liss, south-southwest.
The A1, also known as the Great North Road, is the longest numbered road in the United Kingdom, at 410 miles (660 km). It connects London, the capital of England, with Edinburgh, the capital of Scotland. The numbering system for A-roads, devised in the early 1920s, was based around patterns of roads radiating from two hubs at London and Edinburgh. The first number in the system, A1, was given to the most important part of that system: the road from London to Edinburgh, joining the two central points of the system and linking the UK's (then) two mainland capital cities. It passes through or near north London, Hatfield, Welwyn Garden City, Stevenage, Baldock, Letchworth Garden City, Biggleswade, Eaton Socon, Buckden, Peterborough, Stamford, Grantham, Newark-on-Trent, Retford, Doncaster, Pontefract, York, Wetherby, Ripon, Darlington, Durham, Gateshead, Newcastle upon Tyne, Morpeth, Alnwick and Berwick-upon-Tweed.
In Great Britain, there is a numbering scheme used to classify and identify all roads. Each road is given a single letter and a subsequent number. Though this scheme was introduced merely to simplify funding allocations, it soon became used on maps and as a method of navigation. There are two sub-schemes in use: one for motorways, and another for non-motorway roads.
The M27 is a motorway in Hampshire, England. It is 27.9 miles (44.9 km) long and runs between Cadnam and Portsmouth. It was opened in stages between 1975 and 1983, providing the largest two urban areas in Hampshire with a direct motorway link. An extension into the county of West Sussex was planned but never constructed. A number of smaller motorways were proposed, connecting the city centres of Southampton and Portsmouth to the motorway; of these only the M271 and M275 were built. Three sections of the M27 have since been widened to four lanes each way, the first between junctions 7 and 8, the second between junctions 3 and 4, and the third begins at the slip road where junction 11 joins until mid-way to junction 12.
The A3 is a motorway in northeast Switzerland, running diagonally from France toward the southeast border, and passing by Zürich on the way. The total length of the A3 motorway spans roughly 180 kilometres (110 mi), but parts of the road share sections of the A1 and A2 motorways.
Motorway 1 (code: A1, also known as Athens-Thessaloniki-EvzonoiMotorway, and previously as Patras-Athens-Thessaloniki-EvzonoiMotorway the 2nd longest motorway in Greece with a length of 550 km. It is the principal north–south road connection in Greece, connecting the country's capital Athens with the regions of Thessaly and Macedonia, as well as the country's second largest city, Thessaloniki. It starts from Neo Faliro in Attica and continues north to reach the Evzonoi border station, on the Greek border with North Macedonia.

The Brotherhood and Unity Highway, officially classed as the M-1 highway, was a highway that stretched over 1,182 km (734 mi) across Yugoslavia, from the Austrian border at Jesenice in the northwest via Ljubljana, Zagreb, Belgrade and Skopje to Gevgelija on the Greek border in the southeast. It was the main highway in the country, connecting four constituent republics and the country as a whole with neighboring highways.
The A601(M) was a motorway in Carnforth, Lancashire, England. It was at the time of its downgrade a 1.3 miles (2.1 km) long dual carriageway, meeting the M6 at Junction 35. It is no longer a motorway but remains open, as part of the B6601 and A6070.
The M63 motorway was a major road in the United Kingdom. It was completely renumbered, in 1998, to become a substantial part of the M60 motorway which orbits part of Greater Manchester.
The motorways in North Macedonia are called avtopat and the name, like its translation in most languages, simply means auto road.
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. As such, and given its geographical location, the road has occasionally been dubbed as the kičma Bosne. The road also serves as the shortest connection of the eastern and southern parts of Croatia.
The A3 motorway is a major motorway in Croatia spanning 306.5 kilometres (190.5 mi). The motorway connects Zagreb, the nation's capital, to the Slavonia region and a number of cities along the Sava River. It represents a major east–west transportation corridor in Croatia and a significant part of the Pan-European Corridor X, serving as a transit route between the European Union states and the Balkans. Apart from Zagreb, where the A3 motorway comprises a considerable part of the Zagreb bypass, the motorway runs near a number of significant Croatian cities.
The A5 motorway is a motorway in Croatia spanning 83.6 kilometres (51.9 mi). It connects Osijek, the largest city in Slavonia region, to the Croatian motorway network at the Sredanci interchange of the A3 motorway. The A5 represents a significant north–south transportation corridor in Croatia and is a part of the European route E73. The A5 motorway route also follows Pan-European corridor Vc. In addition to Osijek, the A5 motorway also passes near Đakovo and Beli Manastir.
The A404 is a road in the United Kingdom that starts at Paddington in London and terminates near Maidenhead in Berkshire. It is 44.6 miles (71.8 km) long.
Zagreb bypass is a U-shaped motorway partially encircling Zagreb, Croatia. The largest part by far, between Jankomir and Ivanja Reka interchanges, was built between 1977 and 1979, while the Ivanja Reka – Sveta Helena section was built between 1996 and 1999. The bypass is 48.9 kilometres (30.4 mi) long, tracing around the city from the northwestern suburb of Zaprešić to Sveta Helena in the northeast. The bypass crosses the Sava River twice and comprises a bridge across the Sava-Odra floodwater overflow canal. As the busiest sections between Jankomir and Buzin interchanges carry traffic volume of approximately 45,000 AADT, it is the most heavily used motorway sector in Croatia.

Controlled-access highways in Romania are dual carriageways, grade separated with controlled-access, designed for high speeds. There are two types of highways, motorways and expressways, with the main difference being that motorways have emergency lanes and slightly wider lanes. The maximum allowed speed limit for motorways is 130 km/h (81 mph), while for expressways the limit is 120 km/h (75 mph). There are no toll roads, but a road vignette is required.
The Highways in Albania are the central state and main transport network in Albania. The motorways and expressways are both part of the national road network. The motorways are primary roads with a speed limit of 110 kilometres per hour (68 mph). They have white on green road signs such as in Italy and other countries nearby. The expressways are the secondary roads, also dual carriageways, but without an emergency lane. They have a speed limit of 90 kilometres per hour (56 mph). They have white-on-blue road signs.
