Except for the Chuilu Cliff Trail from Patakang to Laohsi Creek, the Liwu River Trail from Tienhsiang to Pilu Giant Tree, and side branches of the Hohuan Trail such as those from Holiu to Lienhua Pool and from Huitouwan to Meiyuan, the rest of the trail became part of today's Central Cross-Island Highway.
除了巴達岡到荖西溪的「錐麓大斷崖古道」；天祥到碧綠神木的「立霧溪掘鑿曲流古道」與「合流到蓮花池」、「迴頭彎到梅園」等其他合歡古道支線之外，其餘路段皆成了現今的中橫路段。
