Batangas City
Another extension to Bauan, called the Batangas City–San Pascual–Bauan Road is proposed by the Department of Public Works and Highways as an alternative to the existing national road between Batangas City and Bauan. The project is expected to decongest the existing national road, whose traffic demand reached beyond capacity due to roadside establishments, industrial areas, and the Batangas Port, and increase economic development in the Batangas City–Bauan area. The proposed alignment of the toll road will start at the present terminus of STAR Tollway at barangay Balagtas, pass through the northern rural barangays of Batangas City and San Pascual, and end at the national road to Mabini at barangay Manghinao in Bauan. The proposed toll road is being constructed as an at-grade bypass only, connecting with Diversion Road, with right of way acquisition and construction works started on February 21, 2018.
