Synonyms & antonyms
  • Related幹線道路かんせんどうろNeutralA concrete trunk road linking major cities. 「大動脈」 is mostly figurative—a lifeline of traffic or logistics—or the aorta itself.
  • Related主要道路NeutralA plain, objective term for a main road, without the lifeline metaphor that 「大動脈」 carries.

Use 「大動脈」 for the aorta or, figuratively, a vital traffic or logistics artery, as in 「東海道の大動脈」. For an actual trunk road say 「幹線道路」; 「主要道路」 is a neutral, non-metaphorical way to say main road.
