Transport in Belgium is facilitated with well-developed road, air, rail and water networks. The rail network has 2,950 km (1,830 mi) of electrified tracks. There are 118,414 km (73,579 mi) of roads, among which there are 1,747 km (1,086 mi) of motorways, 13,892 km (8,632 mi) of main roads and 102,775 km (63,861 mi) of other paved roads. There is also a well-developed urban rail network in Brussels, Antwerp, Ghent and Charleroi. The ports of Antwerp and Bruges-Zeebrugge are two of the biggest seaports in Europe. Brussels Airport is Belgium's biggest airport.
Transport in the Czech Republic relies on several main modes, including transport by road, rail, water and air.

Transport in Greece has undergone significant changes in the past two decades, vastly modernizing the country's infrastructure and transportation. Although ferry transport between islands remains the prominent method of transport between the nation's islands, improvements to the road infrastructure, rail, urban transport, and airports have all led to a vast improvement in transportation. These upgrades have played a key role in supporting Greece's economy, which in the past decade has come to rely heavily on the construction industry.
Transport in Hungary relies on several main modes, including transport by road, rail, air and water.
Transport in Poland involves air, water, road and rail transportation. The country has a large network of municipal public transport, such as buses, trams and the metro. As a country located at the 'cross-roads' of Europe, Poland is a nation with a large and increasingly modern network of transport infrastructure.
Transport in Pakistan is extensive and varied, and serves a population of over 240 million people. In recent years, new national highways have been built, with the addition of motorways which have improved trade and logistics within the country. Pakistan's rail network owned by Pakistan Railways is also undergoing expansion in recent years. Airports and seaports have been built with the addition of foreign and domestic funding. Transportation challenges in developing countries like Pakistan are escalating due to poor planning, inadequate governance, and corrupt practices. Consequently, these nations are grappling with a significant crisis in their transportation systems.
Transport in Spain is characterised by a network of roads, railways, trams, air routes, and ports. Its geographic location makes it an important link between Europe, Africa, and the Americas. Major forms of transit generally radiate from the capital, Madrid, located in the centre of the country, to link with the capitals of the autonomous communities.
Switzerland has a dense network of roads and railways. The Swiss public transport network has a total length of 24,500 kilometres and has more than 2600 stations and stops.
A tunnel is an underground or undersea passageway. It is dug through surrounding soil, earth or rock, or laid under water, and is enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods.
The Gotthard Road Tunnel in Switzerland runs from Göschenen in the canton of Uri at its northern portal, to Airolo in Ticino to the south, and is 16.9 kilometres (10.5 mi) in length below the St Gotthard Pass, a major pass of the Alps. At time of construction, in 1980, it was the longest road tunnel in the world; it is currently the fifth-longest. Although it is a motorway tunnel, part of the A2 from Basel to Chiasso, it consists of only one bidirectional tube with two lanes. With a maximum elevation of 1,175 metres (3,855 ft) at the tunnel's highest point, the A2 motorway has the lowest maximum elevation of any direct north-south road through the Alps.
The Fréjus Road Tunnel is a tunnel that connects France and Italy. It runs under Col du Fréjus in the Cottian Alps between Modane in France and Bardonecchia in Italy. It is one of the major trans-Alpine transport routes between France and Italy being used for 80% of the commercial road traffic.
England has a dense, multimodal transportation infrastructure. The Department for Transport is the government department responsible for the transport network in England. The Secretary of State for Transport is the member of the cabinet responsible to Parliament for the Department for Transport.
The A 4 is a Portuguese motorway with a length of 63 kilometres, running from Matosinhos to Amarante, where it narrows to become an IP road, signed as IP4 .
The Belgrade bypass or Belgrade city road bypass is a U-shaped, 78-km long motorway partially encircling the city of Belgrade, the capital of Serbia.
The Tel Aviv–Jerusalem railway is a railway line in Israel connecting the cities of Tel Aviv and Jerusalem. The line serves as the main rail link between the two cities, complementing the old Jaffa–Jerusalem railway. As such, the railway is often referred to in Israel as the high-speed railway to Jerusalem to distinguish it from the older, longer and slower line. In spite of that name, the line is not high-speed under the definition used by the International Union of Railways: both its design speed of 200 km/h (125 mph) and its current operational speed of 160 km/h (99 mph) are below the 250 km/h (155 mph) threshold used by the UIC to define high-speed railways, and it is traversed by IR's regular rolling stock instead of the UIC requirement for specially-designed high-speed trains.
The A1 motorway is a motorway in Serbia and at 588 kilometers (365 mi) it is the longest motorway in Serbia. It crosses the country from north to south, starting at the Horgoš border crossing with Hungary and ending at the Preševo border crossing with North Macedonia. As a part of the European route E75 and Pan-European corridor X, connecting 4 of 5 largest Serbian cities, it is the most vital part of the Serbian road network.
The Great Istanbul Tunnel is an under-construction multi-use highway and railway undersea tunnel in Istanbul, Turkey to cross the Bosphorus strait. It will be the third and the longest tunnel crossing the Bosphorus strait, at a length of 6.5 km, surpassing the Eurasia Tunnel at 5.4 km and the Marmaray Tunnel at 13.5 km.
The Meseș Tunnel is a future automotive tunnel located near Zalău, in Sălaj County, Crișana, Romania, which is planned be part of the route of the A3 Transylvania Motorway, specifically the Poarta Sălajului - Zalău segment (12,9 km). It is named after the Meseș Mountains, the mountain range belonging to the Apuseni Mountains, which forms part of the Carpathians. When completed, it will be the longest road tunnel in Romania, being 2.89 kilometres (1.80 mi) long,
