The section between Toucheng, Yilan and Su-ao, Yilan was completed in January 2006.
Hsuehshan Tunnel between Pinglin, Taipei and Toucheng, Yilan is 12.9 km long. It is the fifth longest road tunnel in the world.
Extension to Hualian is planned, but the construction is suspended due to environmental concerns.
Pinglin IC located in Taipei water preservation area, is temporarily opened before the Syueshan Tunnel completed. It will not open to public due to environmental protection issues. The water on the freeway is collected by the water processing plant to prevent polluting the preservation area.
Su-Hua Freeway (蘇花高速公路) is a future freeway project executed by Taiwan Area National Expressway Engineering Bureau (zh:國道新建工程局). It will be constructed between Suao, Yilan and Ji-an, Hualien. It may cost over 100 billion NT dollars to build. Due to environmental protection issues, this project is temporarily suspended. The next item will be Hua-dong Freeway and South Link Freeway.
In 2008, a substitution way of Su-Hua Highway (Provincial Highway No. 9) was suggested, which was named "Suhuati." It will be between Nan-ao, Yilan and Heping, Hualien, and would cost approximately 30 billion NT dollars to build.
In 2010, the project was renamed to Suhuagai, where the project was intended to improve dangerous sections between Suao and Chongde; MOTC said it will start construction in 2011.[1]
