The Taipei Metro Nei-hu Line is a Phase 2 Brown Line extension currently under construction. The line is a medium capacity system, most of which is on an elevated corridor except near Sung-shan Airport. When completed, it will have a total length of 14.8 km and will connect directly to the Mu-zha Line, providing transfer to Nei-hu, Nan-gang and Mu-zha. It is expected to be finished in June, 2009. Our project aims to examine the construction of it and discuss the effects it will have on the people. In order to combine the scenery and culture of Nei-hu, there is a rich diversity in the construction and design of part of the stations. Take Taipei Song-shan Airport Station for example, it is designed based on the theme “the story of flight.” Jian-nan Road Station is designed according to the theme “Mountain,” while Xi-hu Station is designed based on the theme “the Dance of Butterflies.”

Nei-hu District is one of Taipei City's twelve districts. Its attractions include Da-hu Park, famous for its picturesque footbridge, and Bi-shan Temple, a large Taoist temple. The mountains in Nei-hu boast a panoramic view of Taipei, and an extensive network of hiking trails criss-crosses the mountainous regions of the northern part of Nei-hu. In the vicinity of Bi-shan Temple are a number of other Taoist and Buddhist temples, as well as orchards and fruit farms, where tourists can pick their own fruit. For these reasons, many hikers, holidaymakers, and local residents enjoy paying a visit in Nei-hu.
