In Albania, major cities are linked with either new single/dual carriageways or well maintained State Roads marked as "SH" (Rrugë Shtetërore).
There is a dual carriageway connecting the port city of Durrës with Tirana, Vlorë, and partially Kukës.
The crust of the Earth is composed of a great variety of igneous, metamorphic, and sedimentary rocks. The upper part of the mantle is composed mostly of peridotite, a rock denser than rocks common in the overlying crust.
In Australia, a highway is a distinct type of road from freeways, expressways, and motorways.
The word highway is generally used to mean major roads connecting large cities, towns and different parts of metropolitan areas.
Partly by analogy to what is known about the Moon, Earth is considered to have differentiated from an aggregate of planetesimals into its core, mantle and crust within about 100 million years of the formation of the planet, 4.6 billion years ago.
The primordial crust was very thin and was probably recycled by much more vigorous plate tectonics and destroyed by significant asteroid impacts, which were much more common in the early stages of the solar system.
The continental crust is typically from 30 km (20 mi) to 50 km (30 mi) thick and is mostly composed of slightly less dense rocks than those of the oceanic crust.
Some of these less dense rocks, such as granite, are common in the continental crust but rare to absent in the oceanic crust.

There are three official Motorway segments in Albania marked with an "A" (Autostradë): Thumanë–Milot–Rrëshen–Kalimash (A1), Levan–Vlorë (A2), and partly Tirane–Elbasan (A3).
Most rural segments continue to remain in bad conditions as their reconstruction has only begun in the late 2000s by the Albanian Development Fund .
