Sandiao Ridge Eco-Friendly Tunnel Introduction
There are nine old tunnels between Ruifang Station and Shuangxi Station, which gives rise to the Taiwanese proverb "One coin drills nine holes." Among them, four old tunnels have been developed into bike paths. The ecologically friendly Sandiaoling tunnel, reopened after being abandoned for 30 years, totals 3.19 kilometers in length, making it the first "reinforced concrete bike path" in Taiwan. The designer utilized a water pool design to create a stunning mirror reflection that transitions from darkness to light at the tunnel entrance, harmonizing with the lush green mountains of Sandiaoling. There is a possibility to encounter trains, and for safety, bicycles must be pushed through the dual-access Shanguazai tunnel to the hanging bridge.
