Baguashan Tunnel
From Wikipedia, the free encyclopedia
Baguashan Tunnel (Traditional Chinese: 八卦山隧道) on Provincial Highway No. 76 transverses Baguashan (八卦山) between Lincuo IC. (林厝交流道) and Jhongsing SIC. (中興系統交流道). The length of the north tube for westbound traffic is 4928 m. The length of the south tube for eastbound traffic is 4935 m. Connecting Yuanlin, Changhua and Caotun, Nantou (zh:草屯), its opening significantly reduced the travel time between Changhua and Nantou.
It was the longest highway tunnel in Taiwan when opened to traffic in April 2005, until the top rank moved to Hsuehshan Tunnel in National Highway No. 5 in June 2006. It is now the second longest highway tunnel.
