Construction of National Highway 1 overpass connecting Phan Thiet Expressway is about to start

On February 5, Mr. Nguyen Cong Hop, Deputy Director of the Phan Thiet - Dau Giay Expressway Management Board, said that the Thang Long Project Management Board has coordinated with Binh Thuan province to mobilize people to hand over the site to soon start construction of the Ba Bau intersection overpass on National Highway 1.

This is an additional item after the Phan Thiet - Dau Giay expressway is put into operation from the end of April 2023.

"Currently, the Board is completing related procedures to soon start construction of the overpass. If all goes well, the project is expected to start in April 2025," Mr. Hop informed.

According to the approved design, the intersection connecting to National Highway 1 (Ba Bau intersection) was adjusted to an intersection with four branches entering and exiting National Highway 1 from the connecting route and the new Ham Kiem - Tien Thanh route (expressway connecting road), each branch has two lanes.

Build an overpass on National Highway 1 with four lanes, arrange a roundabout under the overpass and expand the existing Suoi Sop bridge.

Add some service roads with rural traffic scale and add horizontal and vertical drainage systems.

In addition, at Phan Thiet intersection, add a right turn from the highway with a length of 1.2km. Scale of two lanes, road surface width 7m, right shoulder width 3m and left shoulder width 1m.

Previously, in July 2023, the People's Committee of Binh Thuan province proposed to build an additional overpass at Ba Bau intersection to relieve traffic conflicts.

The solution proposed by this province is to soon invest in building an overpass on National Highway 1, the section passing through Ba Bau intersection (at Km 1717+593, Ham Kiem commune).

At the same time, open another right-turning branch road, in the direction from Dau Giay to Phan Thiet before reaching Ba Bau intersection, to regulate the flow of vehicles entering and exiting the highway, ensuring safer and more convenient vehicle movement.
