The major cities along its route heading from north to south are New Taipei City, Taoyuan, Hsinchu, Taichung and Tainan.

Currently, approximately 286 kilometers of the route has been completed and opened to traffic for operation, while remaining portions will be implemented in various sections between now and the year 2026.


The project features a number of new bridges and viaduct structures that utilize frontage roads underneath the viaducts to better serve the local traffic in communities along its route length.
