Notes

The section between Toucheng Township and Su'ao Township of Yilan County was completed in January 2006.

Xueshan Tunnel between Pinglin, Taipei and Toucheng, Yilan is 12.9 km long. It is the fifth longest road tunnel in the world.

Extension to Hualien City 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

Su-Hua Freeway (蘇花高速公路) is a future freeway project executed by Taiwan Area National Expressway Engineering Bureau. It will be constructed between Su-ao, Yilan and Ji-an, Hualien. It may cost over 100 billion New Taiwan 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.

A re-alignment of Su-Hua Highway

In 2008, a realignment of the Su-Hua Highway was suggested, which was named "Suhuati." It would be between Nan-ao, Yilan and Heping, Hualien, and would cost approximately NT$30 billion to build.

In 2010, the project was renamed to Suhuagai. The project was intended to improve dangerous sections between Suao and Chongde; the MOTC said it will start construction in 2011.
