Provincial Highway 1 (Chinese: 台1線; pinyin: Tái Yī Xiàn) is a 461.081 km (286.502 mi)-long Taiwanese provincial highway that starts in the north of the country near Taipei Main Station and ends in the south at Fangshan, Pingtung County. It intersects with Provincial Highway 9 and Provincial Highway 26. Before the freeway system was built in Taiwan, this was the primary north-south highway for the island. The highway connects most of the major cities in Taiwan. In most parts of Taiwan, the road is known as The North-South Highway (縱貫公路).
