Introduction to the Penghu Cross-Sea Bridge: The Penghu Cross-Sea Bridge connects the two largest islands in the Penghu Islands, Baisha Island and Xiyu Island. It is one of the main transportation arteries of the Penghu Islands. It spans the most dangerous places in Penghu that are unfavorable for boating. The Penghu cross-sea bridge "Houmen Waterway" was once the longest deep-sea bridge in the Far East. It is a great project. When riding on it, you can feel the strong sea breeze and the magnificent scenery. (Xiyu Township, Penghu County)
