A beltway is a fast main road that goes around a city, not through the centre. The shape is the idea: it sits like a belt around the town, so drivers can skip the busy middle. This is mainly an American word; in Britain people say ring road.

The most famous one is the Capital Beltway around Washington, D.C.最有名的一條就是華盛頓特區周圍的Capital Beltway。

From that road, Americans stretched the word. “Inside the Beltway” means the world of national politics in Washington — the people and the talk inside that circle, not the tarmac itself. When someone calls a story “Beltway news,” they mean it matters to politicians more than to ordinary people.

From that road從那條路 Americans stretched the word美國人把這個詞的意思延伸了出去 'Inside the Beltway' means the world of national politics in Washington「Inside the Beltway」指的是華盛頓的全國政治圈 the people and the talk inside that circle, not the tarmac itself那個圈子裡的人和話題，不是指柏油路本身。When someone calls a story 'Beltway news'當有人說一則新聞是「Beltway news」 they mean it matters to politicians more than to ordinary people他們的意思是這件事對政治人物比對一般人重要得多。

That stretch is informal newspaper talk. The road itself is an ordinary traffic word.

That stretch is informal newspaper talk這種延伸用法是新聞界的非正式說法。The road itself is an ordinary traffic word而這條路本身，就只是一個普通的交通用語。
