The project is managed by Project Management Board 6 under the Ministry of Transport. The investor is a consortium consisting of: Hoa Hiep Company Limited - CIENCO4 Group - Nui Hong Company Limited - Truong Son Construction Corporation - VINA 2 Investment and Construction Joint Stock Company. The project enterprise is Phuc Thanh Hung Investment Joint Stock Company.

Although not the longest project, Dien Chau - Bai Vot is a project with difficult construction terrain and complex geology that requires the use of many high-tech solutions, including: overpasses, large river bridges and mountain tunnels... Of which, Than Vu tunnel is about 1,100m long, the second longest mountain tunnel project on the North - South expressway in the East in the period of 2017 - 2020 (after Nui Vung tunnel on the Cam Lam - Vinh Hao route).
Following the direction of the Prime Minister, on the Dien Chau - Bai Vot expressway section, there are also 4 large terrain overpass projects invested in, including: Xuan Duong 2 bridge, Than Vu 1 bridge, Than Vu 2 bridge and O O bridge.

Among them, Xuan Duong 2 Bridge is the bridge with the tallest pillar on the route, with the tallest pillar reaching 52m. Than Vu 2 Bridge is the longest overpass bridge - nearly 1,300m.
The road tunnel located halfway up Than Vu mountain and the overpasses crossing the old forests blend the Dien Chau - Bai Vot expressway with nature, becoming one of the most beautiful sections on the entire North - South expressway in the East in the period of 2017 - 2020.

Speaking at the opening ceremony, Mr. Le Anh Tuan - Deputy Minister of Transport praised the efforts of agencies, units, and the two provinces of Nghe An and Ha Tinh who united to overcome difficulties to bring the Dien Chau - Bai Vot expressway to the finish line, even though this is one of the most difficult construction routes with mountainous terrain and harsh weather.
In the coming time, the Ministry of Transport requires departments, branches and localities to ensure absolute safety of the expressway during its operation and continue to complete the remaining service roads.
Particularly, Nghe An and Ha Tinh localities have increased investment in connecting traffic systems at highway points to promote potential, strengths, and develop key economic zones in the North Central region.
Previously, with the close direction of the Government, the Prime Minister, the Ministry of Transport, the Investor, the Project Management Board, the consulting units and the construction contractors have made efforts to overcome difficulties, mobilized all resources to speed up the project construction progress, inaugurated and put into operation the first 30km (the section from the beginning of the route connecting with the Nghi Son - Dien Chau Component Project at the QL7 intersection to the QL46B intersection).
The remaining 19km (from the QL46B intersection to the end of the QL8A intersection) due to the large area of weak ground, requiring time to wait for subsidence, has now completed the main route items, put into operation from June 30, 2024.

The completion of the last 19km helps the entire Dien Chau - Bai Vot expressway section to be exploited synchronously over a total length of 49km, shortening the travel time from Hanoi to Nghe An to only about 3.5 hours instead of more than 5 hours as before.
This is also the final piece, marking the completion of all 11 component projects of the project to build a number of expressway sections on the North-South Eastern route in the 2017-2020 period with a total length of 652.86km.
