National Highway 1, Ngoc Hoi - Van Dien section, is being expanded from 4 to 8 lanes, expected to be completed in Quarter I/2026, to alleviate congestion at the southern gateway of the capital.
Rising floodwaters have brought several sections of National Highway 1 through Khanh Hoa to a standstill, forcing authorities to restrict southbound traffic and divert vehicles from the expressway to alternative routes.
