Explanation

Highways are metalled roads connecting distant places that are constructed in such a manner for unobstructed vehicular movement.
The significance of highways from different continents are:
(i) In North America, highway density is high, about 0.65 km per sq km. The TransCanadian Highway links Vancouver in British Columbia (west coast) to St. John.s City in Newfoundland (east coast) and the Alaskan Highway links Edmonton(Canada) to Anchorage (Alaska).
(ii) The Pan-American Highway connectsthe countries of South America, CentralAmerica and U.S.A. - Canada.
(iii) The Trans-Continental Stuart Highwayconnects Darwin (north coast) and Melbourne via Tennant Creek and Alice Springs in Australia.
(iv) Europe has a large number of vehicles and a well-developed highway network.
(v) The important Moscow-Vladivostok Highway serves the region to the east. Due to the vast geographical area, highways in Russia are not as important as railways.
(vi) In China, highways criss-cross the country connecting all major cities. A new highway links Chengdu with Lhasa in Tibet.
(vii) In India, there are many highways linking the major towns and cities.
(viii) In Africa, a highway joins Algiers in the north to Conakry in Guinea. Cairo is also connected to Cape Town.
