The route does not actually reach Xindian; to get there, it is necessary to use Xiulang Bridge, which is actually CR 106 and not PH 64. The road was originally planned as a mostly at-grade boulevard by Taipei County Government named Special Route 1 (特一號道路) from Xiulang Bridge in Zhonghe to Wugu Industrial Park (now New Taipei Industrial Park) through Banqiao and Xinzhuang. Originally the only elevated section of the route was from Dahan Bridge to Minsheng Overpass in Banqiao. In the 1990s, as part of the expressway plans in Taiwan, the Special Route 1 corridor was selected to be upgraded to an expressway-grade Provincial Highway as PH 64. However, due to highway revolts from residents of Xinzhuang and central Wugu, the western portion of PH 64 was realigned to the present route, which bypassed the controversial areas by using the right-of-way near the levees and terminated at Taipei Port in Bali instead of Wugu Industrial Park. The road opened in stages, and was completed by late 2009. The section from Banqiao to Zhonghe opened in 2000, while the section from Banqiao to Bali opened in 2009. Just before the section from Banqiao to Bali opened, the completed expressway was used to host a “car-free” event. Bicyclists and pedestrians had exclusive use of the expressway, and some celebratory events took place to celebrate the completion of PH 64. The entire route is in New Taipei City.
