Ninh Binh–Haiphong Expressway (Vietnamese: Đường cao tốc Ninh Bình–Hải Phòng, labelled CT.08) is a partially completed expressway in Vietnam, running for 109 km connecting Ninh Binh to Haiphong. The route connects the northern coastal provinces of Vietnam with the North-South expressway.
From 2015 to 2021, the expressway was planned as a large part of the former Ninh Binh - Hai Phong - Quang Ninh Expressway as the CT.09 before the Haiphong–Quang Ninh section was split off to the CT.06.
This 50adj=midNaNadj=mid section is estimated to cost VND 10,000 billion and is currently in the financing stage.[1]
