Spanning across an entire continent from one side to the other.
From Latin 'trans-' meaning across, combined with 'continental' from 'continens' meaning continuous land. The word was created in the 19th century to describe railroad and transportation routes crossing continents.
The first transcontinental railroad in America (completed 1869) literally connected the Atlantic and Pacific coasts, shrinking travel time from months to just a week—and it totally changed how people thought about distance!
