Sandiao Line Ecological Friendly Tunnel. There are 9 old tunnels between Ruifang Station and Shuangxi Station, which gave rise to the Taiwanese Hokkien proverb 'one coin drills nine holes'. 4 of these old tunnels have already been converted into bicycle paths. There are 9 old tunnels between Ruifang Station and Shuangxi Station, which gave rise to the Taiwanese Hokkien proverb 'one coin drills nine holes'. 4 of these old tunnels have already been converted into bicycle paths. The Sandiao Line Ecological Friendly Tunnel, which has reopened an old Yilan Line railway tunnel that had been abandoned for 30 years, is 3.19 kilometers long and features Taiwan's first 'rebar bicycle path'. The designer used a water feature at the entrance to create a transition from dark to light, reflecting the lush green mountain scenery of Sandiao Line like a stunning mirror image. There's even a chance to encounter a train. For safety reasons on the section from Sanguazi Tunnel to the wall-mounted boardwalk, bicycles must be walked and guided through.
