The interchange of Highway 3 and Hanoi - Hai Phong expressway is an important road junction between and urban expressway (Ring Road 3) and the Hanoi - Hai Phong expressway and having a total investment of over VND402 billion ($17.3 million).

The project would be a prerequisite for urban development for Gia Lam district, Hanoi.

Being executed from 2019 to 2021, when completed, the intersection will help directly connect Gia Lam district with Long Bien district, creating the most convenient traffic direction, and a prerequisite for urban development for Gia Lam district in particular and Hanoi in general.

The interchange starts at Km 0-420 (connecting to Co Linh road) and ends at Kilometer 1+ 065.74 with the length of nearly 1.5 kilometer and the width of between 33 – 51meter, directly connecting Long Bien – Thach Ban road with Hanoi – Hai Phong expressway.

It will directly connect the two districts of Gia Lam and Long Bien in Hanoi.

The area of the interchange is 620 meter long and 26.50 meter wide with the synchronous greenery and lighting system. Previously, there was no expressway for – to Hai Phong from Co Linh street or Vinh Tuy bridge but only byways.

When completed, the project will help vehicles enter and exit the highway conveniently and safely, shorten the journey, and optimize the investment efficiency of Ring Road 3, Hanoi - Hai Phong expressway and Co Linh road. The conjunction also helps reducing the congestion in this entrance to Hanoi as well as promoting socio-economic development of the city.
