Hanoi is accelerating construction of the service road for the Ring Road No.4 project, with the goal of completing it in the fourth quarter of this year.

The 59-km service road runs across seven districts of Soc Son, Me Linh, Dan Phuong, Hoai Duc, Ha Dong, Thanh Oai and Thuong Tin. It allows a maximum speed of 80 kph.

Total investment capital is estimated at over VND5.38 trillion ($222 million).

The Ring Road No.4 has a total length of 112.8 km, running through Hanoi and its two neighboring provinces of Hung Yen and Bac Ninh,  and covers a combined area of 1,341 ha,  with total cost estimated at over VND85.8 trillion ($3.6 billion).

The project is scheduled for completion by 2026 and to open to traffic by 2027.

In the initial period, the link will have four lanes with a roadbed width of 17 m, allowing a maximum speed of 100 kph. It will have six lanes upon full completion.
