1.Introduction1.Introduction

• The Hsuehshan Tunnel or "Snow Mountain" tunnel, is the longest tunnel in Taiwan, located on the Taipei-Ilan Expressway (Taiwan National Highway No. 5). The road connects the city of Taipei to the northeastern county of I-lan, cutting down the journey time from two hours to just half an hour. One of the key aims of constructing the tunnel was to connect the western coast of Taiwan, where 95% of the population live, to the eastern coast of the island and in doing so tackle the unbalanced development on the island.

3.Effects and Significance3.Effects and Significance

1) The 31km Taipei-ilan Freeway will link the nation's prosperous western half with the less developed eastern half.

2) The Taipei-Ilan Freeway will balance regional developments and furnish people with a convenient and fast means of transportation.

3) More than 30,000 cars a day are expected to use the tunnel, with the figure expected to rise sharply on weekends.
