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.

The substitution way of Su-Hua Highway
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]
The contests of Suhua Freeway
Beverage
- Suhuagao can solve Suhua Highway's drink such high dangerous、slow speed、insuffient feight。
- Suhua Highway Segment already has a geologial survey by North-Link Line, TRA。
- Suhuagao can bisides existed Beiyigao of vehicle controls－Only allows freight car and trucks and through bus, other small car driving original Suhua Highway ,so ther problerm of roadface being stressed fail will be geratly decreased，and considers maintains of roadface not exist at western freeways, and impossible to happen anything here.
- Improvement of Suhua Highway economic cost may little less than Suhuagao, and make seriouser envionment vandalism high possible。Suhuagao is a large builds，civils、medias、polities persons definitekly will to「tight watch」its envionment vandalism，contrary more easier to be oversighted than Improvement of Suhua Highway。
- Can only build partcular segment，like southern extension of Beiyi Freeways to Nanao Township, make it hasno to cross Dazhuoshuixi Bridge of Tai 9，Just replace most dangerous section of Suhua Highway；Also may only build single tunnel contain double bound driving。As thus just can get more interests with less harm。
- The build of Suhuagao may progressive Hualien Region Tourism Indusry development，and also improvement Hualien Region Tourism Indusry five day of normal days and winter seasons of travel lightseason。
Drink
- Only large vehicles can be served, if small vehicles drives on, it will be high rate og traffic accident. Even to restrict only small vehicles to go on, it still have big roadface maintain problems after several decade years.
- Suhuagao are safer than Suhua Highway though，but it still dangerous than general Freeway：Because Suhuagao have a lot of long tunnels，driving within long tunnels are low security and high difficuly for resuce。
