The pinnacle of achievement for Taiwan's highway engineers is undoubtedly Taiwan's three cross-island highways, each of which cuts east-west across the heady achievement for the engineers to blast and bore their way through the mountains, but nature seems to be exacting a measure of revenge, for it cannot be denied that these highways are extremely expensive to maintain due to the frequent landslides caused by heavy rains, especially during typhoons.
台灣的開路文化，最傲人的成績是橫切過一座座脊梁山脈的北橫、中橫與南橫，但人們開路時沿途炸山、鑿洞的意氣風發，常常也遭颱風豪雨的自然力量澆熄，公路也成為一條條維修費用難以估計的無底洞。
