Accordingly, the investor approved to prepare a feasibility study report under the PPP (public-private partnership) method is Phuong Thanh Traffic Investment and Construction Joint Stock Company.
This is considered an important step forward in the process of upgrading one of the main expressways connecting Hanoi Capital with the southern provinces.
The deadline for submitting the proposal is expected in the second quarter of 2026. Investors will proactively work and negotiate with localities on necessary conditions to implement the project such as: solutions for upgrading and expanding expressways; connecting works, serving people's lives; site clearance and resettlement plans; material supply sources, excess material dumping points during construction...
The Vietnam Road Administration is fluent in receiving documents and proactively coordinating with investors in the process of preparing a feasibility study report.
Previously, according to the proposed plan of Phuong Thanh Traffic Investment and Construction Joint Stock Company sent to the Vietnam Road Administration, the Phap Van - Cau Gie expressway will be expanded following the current route.
Based on the planning and research of many different options, the investor recommended that competent authorities consider the scope of project implementation over a total length of nearly 30km. Starting point at Phap Van intersection (intersection between Phap Van - Cau Gie expressway and Hanoi Ring Road 3); ending point at the front of Dai Xuyen intersection (Km211+000 of Cau Gie - Ninh Binh expressway).
In terms of scale, the Phap Van - Ring Road 4 - Khe Hoi section passes through many residential areas. To limit the volume of site clearance and reduce the impact on the lives of people on both sides of the road, investors propose a plan to arrange a overpass running along the route, located on the strip of land between the highway and the service road.
In particular, the Phap Van - Ring Road 4 section has 3 lanes on each side of the overpass; the Ring Road 4 - Khe Hoi section has 2 lanes on each side of the overpass.
For the Khe Hoi - Cau Gie section, mainly passing through agricultural land, to reduce investment costs, the studied option is to arrange to go low and expand the existing road, ensuring the scale of 10 expressway lanes. The low-pass section has a design speed of 100km/h, while the overpass section reaches a design speed of 120km/h.
With the above option, the total investment of the project is more than VND 22,146 billion, the lowest cost among the options being studied. If approved, the feasibility study report will be prepared, submitted for appraisal and approval in the period from the fourth quarter of 2025 to the second quarter of 2026; construction from the first quarter of 2027 to the second quarter of 2029, and put into operation from the third quarter of 2029.
