The Taroko Gorge Road in Taiwan is another mountain route made by carving out rocks, like the Guoliang Tunnel road. Despite its name, the Central Cross-Island Highway is a narrow and winding mountain road, and only a bus can barely pass by at a time. But the highway itself is truly an engineering masterpiece, as it cuts through the mountains and joins the East and West Coast. It's full of blind curves, sharp turns, and narrow paths leading through cliffs and mountains.
The curvy and mountainous Hehuanshan Road is currently the only paved road leading across the Central Mountains via the famous Taroko Gorge. Climbing up to Wuling, at 3,275 metres above the sea level, is the highest automobile pass in Taiwan.
The Suhua Highway is one of the most scenic drives in Asia. The road hugs the cliffs of Taiwan's east coast, from Su'ao to Hualian. With a portion built alongside very steep cliffs high above the Pacific Ocean, it is a dangerous yet scenic drive.
