For a long time, the Dong Dang - Tra Linh expressway project has been assessed not only as a key traffic project but also has strategic significance in terms of politics, economy, culture, society, national defense, security and foreign affairs.
When completed, the expressway will connect with the Huu Nghi - Chi Lang and Bac Giang - Lang Son projects, forming a vital trade axis from Vietnam to China and Europe, contributing to improving the competitiveness of the economy and creating new development momentum for the Northeast region.

This is also part of the road network planning for the period 2021-2030, with a vision to 2050, approved by the Prime Minister under Decision No. 1454/QD-TTg dated September 1, 2021.
According to Associate Professor. Dr. Tran Chung - Chairman of the Vietnam Association of Road Traffic Investors, in recent years, it can be affirmed that the implementation of key infrastructure projects and works has become an important driving force to promote the socio-economic development of the country and localities.
Infrastructure, including opened transport infrastructure, not only connects regions but also creates opportunities to attract investment, develop trade and tourism, contributing to improving people's lives.
The Dong Dang - Tra Linh Expressway Phase 2 project has many special meanings. This is a vital expressway opening the way for Cao Bang and the northern mountainous provinces to unleash potential, creating new development space for border gate economy, logistics services and border trade exchange.
"Dong Dang - Tra Linh Expressway is also a testament to the capacity of domestic enterprises in mastering large and complex projects" - Mr. Chung said.

The completion of this project will become an important highlight, contributing to realizing the goal of developing a synchronous and modern transport infrastructure, bringing Vietnam forward faster in the era of integration and growth.
Before the good news of the expressway being accelerated, Mr. Nghiem Van Thanh (Quang Uyen commune) expressed his excitement: "People have been looking forward to the expressway for a long time, but after seeing it built for a few years, everyone is happy, and their children and grandchildren will return to Hanoi to have less hardship."
