Baguashan Tunnel
The 218th longest tunnel in the world
The Baguashan Tunnel is the highway tunnel of Provincial Highway No. 76, Taiwan, transversing Baguashan between Lincuo IC. and Zhongxing JCT.. The length of the north tube for westbound traffic is 4,928 m (3.062 mi). The length of the south tube for eastbound traffic is 4,935 m (3.066 mi). Connecting Yuanlin, Changhua and Caotun, Nantou, 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 in Taiwan.
