The '''Principal Highway''' was the first Crown-funded highway in Centralia. Stretching from Centralia's west coast in [[ButtercupBay]] to the [[Discordantia]] border in [[EdgeCity]], the Principal Highway was established by [[PrincessMeredith]] early in her reign as a way to promote trade between various regions of Centralia.
The present-day Principal Highway exists in two segments, the '''West Principal Highway''', designated '''C-1''', which runs west from [[QueenCity]] to the coast at [[ButtercupBay]], and the '''East Principal Highway''', designated '''C-6'''<<FootNote(A portion of the East Principal Highway is also designated as '''C-5''' as a result of the cancellation of a proposed freeway alignment of C-5 between [[FoxGrove]] and Queen City.)>>, which runs east from Queen City to the Discordantia border in [[EdgeCity]]. The two segments technically do not connect, as continuity is broken by the so-called "[[Honeycomb]]" freeway network in downtown Queen City.
While the modern alignment of the Principal Highway is a fully controlled-access freeway, the original alignment, dating back to Princess Meredith's reign, still exists in several discontinuous stretches, and is fully signed as a historic route.
