Sandiaoling Eco-friendly Tunnel
The Old Sandiaoling Tunnel is located at the junction of Ruifang District and Shuangxi District in New Taipei City. It has a total length of 1,852 meters and was opened on September 21, 1922 (the 11th year of the Taisho era of Japan). It was originally a railway tunnel of Yilan Line. In 1985, the new Sandiaoling Tunnel was launched, and the old tunnel was closed. It is currently listed as a historic building of New Taipei City and has not yet been opened to the public due to safety reasons.
There are nine old tunnels on the way from Ruifang Station to Shuangxi Station, from which the Taiwanese proverb "One Yen through nine holes" was derived. Among them, four old tunnels have already been transformed into bicycle paths, while the old Sandiaoling Tunnel and Sanguazi Tunnel have not yet been renovated and connected. The combination of railway and cycling tourism between Ruifang and Shuangxi, similar to the promotion of low-carbon travel on Route 2 Taiwan, is expected to bring back the past glory of Ruifang and Shuangxi.
