The project got off the ground in 2008 and was originally scheduled for completion in 2014.
However, in 2019, the project just entered its first operational phase, with more than 19 kilometers opened to traffic, connecting the former Ha Dong District with the former Thanh Oai District.
The remaining stretch still stalled as compensation and site clearance obstacles persisted.
Once fully completed, the route is expected to become the longest arterial road linking Hanoi’s inner and outer areas.

It is also seen as a critical solution for easing congestion on major transport corridors such as National Highway 6, Phap Van - Cau Gie Expressway, and National Highway 1.
During the 2024-25 period, the municipal People’s Committee held multiple meetings and issued a series of directives aimed at resolving outstanding issues.
The municipal administration, in coordination with communes, has cleared remaining site clearance bottlenecks and urged investors and contractors to accelerate construction.
The initial 19-kilometer section is now operating stably.

Meanwhile, more than seven kilometers of the subsequent section, extending to Provincial Road 428, has reached over 90 percent completion.
Half of this stretch has already been temporarily opened to traffic.

Contractors said that asphalt surfacing is underway on the final one-kilometer segment, with completion expected within the next two weeks.
Landscaping, street lighting, and traffic safety infrastructure are also being finalized.
If progress continues as planned, the over-seven-kilometer section is expected to be fully opened to traffic in time for the upcoming Lunar New Year holiday, which is due next month.

Meanwhile, machinery has been mobilized to carry out construction simultaneously along the remaining 15-kilometer stretch.
Contractors are focusing on roadbed fillings and treatment of weak soil foundations.
Site clearance has now been completed through to National Highway 1, near Cau Gie Interchange.
Once fully opened, the southern axis road will connect directly with National Highway 1, facilitating the development of urban clusters along the corridor.
In addition, the route will link with Ring Road No. 4, opening up new urban development space in the southern and southwestern areas of the capital.
