Alaska, and as far south as Yaviza in Panama but this only clocks in 7,500 miles.

阿拉斯加，南至巴拿马的 Yaviza， 但这仅在 7, 500 英里内计时。

One idea is to simply extend the already existing pan-American highway from Yaviza in Panama out to the Caribbean coast through the less delicate ecosystems and establish a ferry link with a row network over in Colombia.

一种观点是，直接将现有的泛美公路从巴拿马的亚维萨通过不那么脆弱的生态系统延伸到加勒比海岸，并在哥伦比亚建立一个轮渡网络。

And it is called a Gap because, for more than a hundred kilometers here between the Colombian town of Turbo and the Panamanian town of Yaviza, there aren't any roads at all, and there isn't even really any civilization either.

它之所以被称为地堑，是因为在哥伦比亚的图尔博镇和巴拿马的亚维萨镇之间的一百多公里处，根本没有任何道路，甚至也没有任何文明。
